falcon's Issues

Should Falcon also capture status bar contents and displayed keyboard?

When screen orientation is landscape, screenshot taken previously activity (portrait) also.

Getting exception

Please help.

i'm getting this exception

"Attempt to read from field 'android.graphics.Rect android.view.View$AttachInfo.mTmpInvalRect' on a null object reference"

This exception occurs occasionally.
Could not find exact issue.

Calling .takeScreenshotBitmap() inside a ScheduledThreadPoolExecutor to take ScreenShots continuously (5 ScreenShots per sec).

Should i call the function .takeScreenshotBitmap() on UI thread?

Thanks.

Does not work when the activity contains mapview

If there is a mapview in the layout it is being rendered as black solid with only Google logo on it.

FalconSpoon class present in 2.0.0 release

Probably due to not cleaning the local build, it is present in aar. New release will follow.

Crash when call not in UI Thread

Sometimes there is a fall.
I think it is related to the display of dialogs

Maybe you can add catch to this block:

      activity.runOnUiThread(new Runnable() {
        @Override
        public void run() {
          try {
            drawRootsToBitmap(viewRoots, bitmap);
          } finally {
            latch.countDown();
          }
        }
      });

Thanks for your work.

sluggish issue in case of scrolling.

I was using this code.
I am facing sluggish issue while taking the screenshots during scrolling. Just a little discontinuity, so no smooth scrolling.
I tried debugging, and I narrowed down which part of the code is giving this, where we are posting a task on UiThread to capture screenshots and overlap in the case of multiple views.
activity.runOnUiThread(new Runnable() {
@OverRide
public void run() {
try {
drawRootsToBitmap(viewRoots, bitmap);
} finally {
latch.countDown();
}
}
});

  latch.await();
}

But I did not found any solution.
Can you help me out to make it smooth?

Impossible to capture shadows around components

Hi @jraska,

We dig into your library last week to take screenshots in our android app. You've done an amazing work and results are almost perfect for us.

We were not able to capture shadows around material components: Card, Floating Action Buttons, ... (https://material.io/develop/android/).

On a generic aspect, did you try to capture shadows? Is this something technically possible for you?

Thanks for your work and help!

FalconSpoon dialog screenshot

When writing UI tests with espresso the captured FalconSpoon screenshot does not include the dialog I expect to be there.

Open Activity
Trigger dialog (AlertDialog.create...show());
verify that the dialog is present with:
onView(withText("hello dialog").check(matches(isDisplayed()));
FalconSpoon.screenshot(getActivity(), "Dialog_test");

How to take screenshot of textureview alongwith otherviews ?

Falcon misses DialogFragments and AlertDialogs

I'm trying to use Falcon in my app, but it seems to don't save the view of DialogFragments and AlertDialogs. It seems strange, but my app looks nearly same as your sample.

public class MyActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        Toast.makeText(this, "Asd", Toast.LENGTH_LONG).show();
        Snackbar.make(findViewById(android.R.id.content), "snackbar", Snackbar.LENGTH_LONG);
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setTitle("Falcon");
        builder.setMessage("Click button below to take screenshot with dialog");
        builder.setPositiveButton("Screenshot", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                try {
                    Falcon.takeScreenshot(this, File.createTempFile("asd", "asd"));
                } catch(IOException e) {
                    e.printStackTrace();
                }
            }
        });
        builder.show();

        // new DialogFragment().show(getSupportFragmentManager(), "DIALOG");
    }

Screenshot has view of activity, with Toast and Snackbar, but the dialog is missing. Same for DialogFragment (commented out).

NullPointerException on Falcon.drawRootToBitmap

When using Falcon with Spoon for instrumentation tests, this exception appears sporadically :

The stack trace:

I could add the full Spoon trace if needed.

Shading or packaging Spoon dependency

We were initially using Spoon + Falcon. We then switched to using Composer + Falcon. We kept using Falcon cause it's a great library and because it will in-turn match Spoon's file location format, which is needed for Composer read more

The problem we are facing now is that Falcon still depends on Spoon, specifically a snapshot version of 2.x. This is causing a lot of problems for build times (gradle always checks for new snapshot) and for remote devs w/ bad network connection.

We love using Falcon but can't afford the dynamic Spoon dependency. We're asking that you package or shade the Spoon dependency with falcon-spoon.

I know it would be weird to shade/package a "snapshot" version. But as long each release of falcon-spoon release notes referenced the Spoon snapshot commit SHA, other devs could decide to update to latest Falcon (or not).

What about Google Maps

Can i take screenshoot of fragment with GoogleMaps ?

Screenshot is Blank for Surfaceview

Hi,

I have used your library for testing but it's saving blank for surface views.

react-native webview canvas Black screen

i use in react-native，code

When I trigger the screenshot i get this

Normally, it should be

canvas tag not right render, i tried Instacapture react-native-shot but Didn't solve my problem。

Status bar screencap

I need a way to screencap the android status bar while falcon or spoon takes a screenshot

Update Readme

Can you update the README to make it clear that you still need to declare

androidTestImplementation 'com.jraska:falcon:2.0.1'

even if you are using

androidTestImplementation 'com.jraska:falcon-spoon-compat:2.0.1'

I initially didn't include the falcon dependency since I assumed that it would be pulled in as part of falcon-spoon-compat. But when I did I got the following runtime error:

java.lang.NoClassDefFoundError: Failed resolution of: Lcom/jraska/falcon/Falcon;
    at com.jraska.falcon.FalconSpoonRule.screenshot(FalconSpoonRule.java:42)
...
Caused by: java.lang.ClassNotFoundException: Didn't find class "com.jraska.falcon.Falcon" on path: DexPathList[[...]]

Failed to resolve Falcon

Hi,

After adding compile 'com.jraska:falcon:1.0.1' in my client-android (on line 62, but not visible here as it is not commited), I get a gradle error: Failed to resolve: com.jraska:falcon:1.0.1.
Do I miss something in the integration?

Thanks

Screenshot not Capturing Overlay

Attempted to take a screenshot of the background, so that I could blur it when showing the dialog. However, Falcon screenshot generates only a Bitmap with the Activity view, and completely ignoring the overlay that contains a Fragment.

For example:

Before showing the dialog, I take a screenshot and blur it before setting it on the image. Here is what I get:

I have examined the screenshot even on file, and see that it completely ignores the overlaying window. I thought multi-window screenshot is supported by Falcon, right? What could be the issue here? Please help.

MediaPlayer and TextureView

I am using https://github.com/yqritc/Android-ScalableVideoView to render a video stream in a TextureView.
I tried FalconSpoon, but the stream is not included in the screenshot.

Is it related to the fact that ScalableVideoView is using MediaPlayer? Any help/workaround is much appreciated.

PreviewView

Hello, help me please. I need to screen cameraview, but screenshot saves everything (buttons etc.) besides previewview

    previewView = findViewById(R.id.view_finder);
    
            imageButtonCapture = findViewById(R.id.camera_capture_button);
    imageButtonCapture.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            SimpleDateFormat mDateFormat = new SimpleDateFormat("yyyyMMddHHmmss", Locale.US);
            File photofile = new File(getBatchDirectoryName(), mDateFormat.format(new Date())+ ".jpeg");
            Falcon.takeScreenshot(MainActivity.this, photofile);

        }
    });
    
    Thanks!

Lollipop update view problem

The falcon library works great across android versions. But i see a concern with lollipop. When the view gets updated, eg: Tap on edit text and start typing. Now use falcon to capture screen . The screen shot has old view where it was not updated. However it works well on jelly bean,kit kat, marshmallow,nougat & Oreo.

Thanks.

Values are not getting reflected in screenshot for AutoCompleteTextView and TextInputEditText

My activity consists of a couple of AutoCompleteTextView and TextInputEditText which are wrapped in TextInputLayout. The issue which I am facing is that when I take the first screenshot, all the details get captured perfectly. Later on, when we edit the AutoCompleteTextView and TextInputEditText fields and if we were to take a screenshot, the details are not reflected.

Could you please help with this issue?

I am using this method for taking screenshots Falcon.takeScreenshotBitmap(activity).

My XML which comprises of AutoCompleteTextView and TextInputEditText fields looks like:

 <com.google.android.material.textfield.TextInputLayout
        style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.ExposedDropdownMenu"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="@string/form_username">

        <AutoCompleteTextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"/>

    </com.google.android.material.textfield.TextInputLayout>

    <com.google.android.material.textfield.TextInputLayout
        style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="@string/form_username">

        <com.google.android.material.textfield.TextInputEditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"/>

    </com.google.android.material.textfield.TextInputLayout>

UPDATE: If we remove the style attribute then it works fine. The issue is that we cannot remove the style attribute because of a few limitations. Would be great if you could help me out with this issue @jraska

Crash: onMeasure() did not set the measured dimension by calling setMeasuredDimension()

The following crash occurs on various layouts like FrameLayout, CoordinatorLayout, RelativeLayout, TabLayout, android.support.v4.widget.NestedScrollView, AppBarLayout, Custom Views, CoordinatorLayout, etc. The crash happens mostly while I touch/swipe on any view which is in a ListView inside ViewPager and tabs. App does not crash without using Falcon.

Following is the same exception but on different layout, rest of the log remains same as above log:

java.lang.IllegalStateException: View with id 2131296790: android.support.design.widget.CoordinatorLayout#onMeasure() did not set the measured dimension by calling setMeasuredDimension()

And sometimes the crash log comes without any layout mentioned:

java.lang.IllegalStateException: onMeasure() did not set the measured dimension by calling setMeasuredDimension()

Screenshot are half size for dialog

I use SpoonFalcon to capture dialog from the material-dialog lib https://github.com/afollestad/material-dialogs

When I capture, I get this:

Nothing on the log, tried 2 times = same results

Add Kotlin examples

java is too old school :P

can not cature webview

In one of my only WebView activities, I can't capture the contents of the WebView. Other Views can be capture.

What about Here Maps?

Usage of Undocumented API (API 29)

Your tool use reflection on some Field which are block by the SDK on API 28. When the target is 28 you get an Exception :
com.jraska.falcon.Falcon$UnableToTakeScreenshotException: java.lang.NoSuchFieldException: Field mWindowTop not found for class class android.view.View$AttachInfo

See the documentation here :
https://developer.android.com/about/versions/pie/restrictions-non-sdk-interfaces

And a working fix is to set system property from adb to disable this restriction :

adb shell settings put global hidden_api_policy_pre_p_apps 1 adb shell settings put global hidden_api_policy_p_apps 1

A solution would be to ask to Google to allow access to the fields mWindowTop, mWindowLeft

Can we not throw UnableToTakeScreenshotException?

Can we not throw UnableToTakeScreenshotException? See https://github.com/jraska/Falcon/blob/master/falcon/src/main/java/com/jraska/falcon/Falcon.java#L65.

I am seeing a few tests fail because of failing to take a screenshot. The tests I am seeing fail are usually very stable. Can we just log the screenshot failure? The screenshots are nice to have but I do not have to have them. I just want my assertions to pass.

Why 2 dependencies?

Could you please explain why following 2 additions are necessary?:

compile 'com.jraska:falcon:1.0.3'
androidTestCompile 'com.jraska:falcon-spoon-compat:1.0.3'

What's the difference between both?

Falcon enhancement to work with AirBnb's Lottie animations

Hello,

I am trying to take multiple screenshots from a Lottie animation which is used in my app but it seems that Falcon takes a screenshot only from the very first instance of the animation and not the whole movement.

Is it a known issue? Can the Falcon be enhanced in order to cover this incompatibility?

Thanks a lot in advance!!!

Best regards,
Nikos

java.lang.NoClassDefFoundError: Failed resolution of: Lcom/squareup/spoon/SpoonRule

Hi,
I'm trying to use FalconSpoon in my espresso tests, but I keep getting java.lang.NoClassDefFoundError: Failed resolution of: Lcom/squareup/spoon/SpoonRule
That's what I have is buld.gradle:

implementation 'com.jraska:falcon:2.0.1'
implementation 'com.jraska:falcon-spoon-compat:2.0.1'
androidTestImplementation 'com.jraska:falcon:2.0.1'
androidTestImplementation 'com.jraska:falcon-spoon-compat:2.0.1'

I also tried to add dependency to spoon itself, but it doesn't help. I'm able to use Falcon methods, only FalconSpoonRule is a problem.
Gradle build is successful, error appears in runtime (tests are written in Kotlin)
I disabled proguard for this build.
Any suggestions?

Screenshot shows activity despite it is closed

I have a test that closes the main activity and then takes a screenshot. On this the activity passed as function parameter can be seen, despite in reality the home dashboard of the phone is shown, is this because the screenshot function uses internally the espresso screenshot function and not UiDevice.takescreenshot()? Is there a way I can use Falcon and get what I am really seeing on the screen?
