执行 createChooser(context,intent,IntentSender) 后不调用 BroadcastReceiver

Question

我想检测用户在向他显示 createChooser() 对话框后选择的应用程序。所以我创建了我的 BroadcastReceiver subclass 这样的：

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;

public class ShareBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d("INFORMATION", "Received intent after selection: "+intent.getExtras().toString());
    }
}

此外，我已将接收器添加到我的 android 清单文件中：

<application>
...
...
...
    <receiver android:name=".helpers.ShareBroadcastReceiver" android:exported="true"/>
</application>

下面是调用 createChooser 对话框的代码：

Intent sendIntent = new Intent(android.content.Intent.ACTION_SEND);
sendIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
sendIntent.setType("image/png");

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP_MR1) {
    Log.d("INFORMATION", "The current android version allow us to know what app is chosen by the user.");

    Intent receiverIntent = new Intent(this,ShareBroadcastReceiver.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(this, 0, receiverIntent, PendingIntent.FLAG_CANCEL_CURRENT);
    sendIntent = Intent.createChooser(sendIntent,"Share via...", pendingIntent.getIntentSender());
}
startActivity(sendIntent);

即使这是一个明确的 PendingIntent 因为我直接使用 ShareBroadcastReceiver class 名称而没有任何 intent-filter，我的广播接收器不会在之后立即回调用户点击选择器对话框，我做错了什么？

你的代码一切正常。您只需要更改 ShareBroadcastReceiver 中的 onReceive 方法中的一行即可捕获 Intent 的 "EXTRA_CHOSEN_COMPONENT" 键：

Log.d("INFORMATION", "Received intent after selection: "+intent.getExtras().get(Intent.EXTRA_CHOSEN_COMPONENT));

在你的日志中你会看到这样的东西（在我的例子中我选择了 Google 保留）：

ComponentInfo{com.google.android.keep/com.google.android.keep.activities.ShareReceiverActivity}

执行 createChooser(context,intent,IntentSender) 后不调用 BroadcastReceiver

BroadcastReceiver is not called after createChooser(context,intent,IntentSender) is executed
