Question

我正在尝试处理新的Android Lollipop MediaProjection API。

我发现（至少在我的股票三星Galaxy S4 jfltexx上）当我开始获得捕获屏幕的权限（ProjectionManager.createScreenCaptureIntent()）的意图时，我在{{我没有获得结果1}}除非我已经检查过了“不要再问”＃34;在前面的尝试...

onActivityResult

结果处理：

private static final int ALLOW_SCREENSHOT_REQ = 102;

{
 ...
        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            System.out.println("request permission");
            startActivityForResult(mProjectionManager.createScreenCaptureIntent(), ALLOW_SCREENSHOT_REQ);
        }
 ...
}

权限对话框显示效果很好，但我的活动被隐藏了，它永远不会转到@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { System.out.println("RebootActivity.onActivityResult(" + requestCode + "," + resultCode + ", data)"); }。

知道出了什么问题？

您是否尝试过这样做：请参见完整示例android-ScreenCapture

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_MEDIA_PROJECTION) {
        if (resultCode != Activity.RESULT_OK) {
            Log.i(TAG, "User cancelled");
            Toast.makeText(getActivity(), R.string.user_cancelled, Toast.LENGTH_SHORT).show();
            return;
        }
        Activity activity = getActivity();
        if (activity == null) {
            return;
        }
        Log.i(TAG, "Starting screen capture");
        mResultCode = resultCode;
        mResultData = data;
        setUpMediaProjection();
        setUpVirtualDisplay();
    }
}

希望它会对你有所帮助。

createScreenCaptureIntent不返回结果
