アクティビティからビデオをキャプチャしたい
これは私のソースコードです
mTempVideoPath = Environment.getExternalStorageDirectory().getName() + File.separatorChar + "Android/data/" + this.getPackageName() + "/files/" + System.currentTimeMillis() + ".mp4";
File videoFile = new File(mTempVideoPath);
try {
if(videoFile.exists() == false) {
videoFile.getParentFile().mkdirs();
videoFile.createNewFile();
}
} catch (IOException e) {
Log.e(getCallingPackage(), "Could not create file.", e);
}
mCurrentVideoURI = Uri.fromFile(videoFile);
Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE );
intent.putExtra( MediaStore.EXTRA_OUTPUT, mCurrentVideoURI);
// preventing it from listing items that aren't on the SD card
intent.putExtra(Intent.EXTRA_LOCAL_ONLY, true);
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
startActivityForResult(intent, CAPTURE_VIDEO);
しかし、私はこのエラーが発生します:
