我試圖模擬點擊錄製按鈕,當啓動MediaStore.ACTION_VIDEO_CAPTURE
時。我的目標是讓應用程序在意圖啓動時立即開始錄製。但是當我運行我的代碼時,我得到以下內容注入到另一個應用程序需要INJECT_EVENTS權限Android
error: java.lang.SecurityException: Injecting to another application requires INJECT_EVENTS permission
。 INJECT_EVENTS權限只允許由系統應用程序。這是我的代碼:
Uri uri = Uri.fromFile(videoFile);
Intent videoIntent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
videoIntent.putExtra(MediaStore.EXTRA_OUTPUT, uri);
videoIntent.putExtra(MediaStore.EXTRA_DURATION_LIMIT, 15);
videoIntent.putExtra("android.intent.extras.CAMERA_FACING", 1);
videoIntent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
startActivityForResult(videoIntent, videoRequest);
new Thread(new Runnable() {
@Override
public void run()
{
Instrumentation inst = new Instrumentation();
inst.sendKeyDownUpSync(KeyEvent.KEYCODE_MEDIA_RECORD);
}
}).start();
是否有另一種解決方案,當意圖啓動時開始記錄?
