我在windows上用Android studio直接打开，能正常运行。我的手机是4.4的。
遇到的问题有push 库到手机上时，代码需要改下：

问题一：
要把原来代码的File.separator改成"/",否则push成了tmp\minicap
修改前：
// 将minicap的可执行文件和.so文件一起push到设备中
device.pushFile(minicapBinFile.getAbsolutePath(), REMOTE_PATH

• File.separator + MINICAP_BIN);
  device.pushFile(minicapSoFile.getAbsolutePath(), REMOTE_PATH
• File.separator + MINICAP_SO);
  修改后：
  // 将minicap的可执行文件和.so文件一起push到设备中
  device.pushFile(minicapBinFile.getAbsolutePath(), REMOTE_PATH
• "/" + MINICAP_BIN);
  device.pushFile(minicapSoFile.getAbsolutePath(), REMOTE_PATH
• "/" + MINICAP_SO);

问题二：
getADBPath里面的adb路径需要写死。
修改前：
if(adbPath != null){
adbPath += File.separator + adbPlatformTools;
}else {
return null;
}
adbPath += File.separator + "adb";
修改后：
if(adbPath != null) {
adbPath += File.separator + adbPlatformTools;
} else {
adbPath = "D:\Software\android_tools\android-sdk\platform-tools";
}
}
adbPath += File.separator + "adb.exe";

使用wm size获取size，其实输出是：
$ adb shell wm size
open: Permission denied
open: Permission denied
Physical size: 720x1280

在调用MiniCapUtil.init()时
size = output.split(":")[1].trim(); 代码就会获取到"Permission denied"这个值。

建议这里可以优化下。用正则，或者取最后一个输出内容，而不是[1]
