Question

我有一个Galaxy Tab 2 7.0 GT-P3110，当我试图有意识地访问相机时会发生奇怪的事情。在一个活动中，我有20个按钮调用访问摄像头的意图，但活动随机下降。有时拍摄的照片是正确的，但有时不会拍摄以下错误：

之后重新启动Activity。源代码是：

public void onTakePicture(View view){
    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(photoPathTemp)));
    startActivityForResult(intent, TAKE_PHOTO_CODE);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == TAKE_PHOTO_CODE && resultCode == RESULT_OK) {
        GalleryButton btn = (GalleryButton) findViewById(getResources().getIdentifier(photoKey, "id", getPackageName()));
        savePhotos(btn.width, btn.height);
        setBackgroundButton(btn, photoPathThumb);
    }
}

提前谢谢。

意图ACTION_IMAGE_CAPTURE杀死活动和app Android 4.1
