我試圖使用Intent.createChooser和從我的Android應用程序共享圖像。圖像被保存到由activity.getExternalMediaDirs()返回的第一個結果。然後我用：Android 6.0.1 - 通過Messenger和Intent.ACTION_SEND共享圖像導致安全異常
mediaScannerConnection.scanFile(imageFilename, "image/png");
這種成功，給人一種URI，如以下到onScanCompleted：
content://media/external/images/media/27578
我再試試這個URI傳遞給系統選擇對話框：
@Override
public void onScanCompleted(String path, Uri uri) {
mediaScannerConnection.disconnect();
Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_TEXT, text);
shareIntent.putExtra("sms_body", text);
shareIntent.putExtra(Intent.EXTRA_SUBJECT, subject);
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
shareIntent.setClipData(ClipData.newUri(activity.getContentResolver(), "Screenshot", uri));
shareIntent.setType("image/png");
shareIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
activity.startActivity(Intent.createChooser(shareIntent, chooserTitle));
}
這似乎適用於大多數選定的目標應用，包括環聊。選擇Messenger時，默認的MMS應用程序似乎什麼也沒有發生。然而有在日誌中的消息：

我沒有MEDIA_CONTENT_CONTROL，但它似乎是無關的共享：http://developer.android.com/reference /android/Manifest.permission.html#MEDIA_CONTENT_CONTROL和「由於媒體消費的隱私而不適用於第三方應用程序」。無論如何，我試着添加這個 - 沒有效果。 –
