打开 Parse 推送通知时出现异常 [关闭]

Question

我设置了Parse push Android SDK 1.7.0 并且可以毫无问题地接收推送。但是，当打开推送通知时，我的应用程序崩溃并出现以下异常：

android.content.ActivityNotFoundException：找不到要处理的活动 意图{act=android.intent.action.VIEW dat=flg=0x1000c000（有 额外）}

我还尝试将ParsePushBroadcastReceiver 子类化为getActivity() 始终返回主活动类，结果相同。以下是完整的堆栈跟踪：

花了几个小时之后。找到了解决方案： 实现您的接收器并扩展 ParsePushBroadcastReceiver 类。

Receiver.java

public class Receiver extends ParsePushBroadcastReceiver {

    @Override
    public void onPushOpen(Context context, Intent intent) {
        Log.e("Push", "Clicked");
        Intent i = new Intent(context, HomeActivity.class);
        i.putExtras(intent.getExtras());
        i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);
    }
}

在清单中使用它，（而不是使用 ParsePushBroadcastReceiver）

项目清单代码：

<receiver
            android:name="your.package.name.Receiver"
            android:exported="false" >
            <intent-filter>
                <action android:name="com.parse.push.intent.RECEIVE" />
                <action android:name="com.parse.push.intent.DELETE" />
                <action android:name="com.parse.push.intent.OPEN" />
            </intent-filter>
        </receiver>

编码愉快！！

这个异常的原因是ParsePushBroadcastReceiver想在这段代码中打开你推送消息中的空uri：

String uriString = null;
    try
    {
      JSONObject pushData = new JSONObject(intent.getStringExtra("com.parse.Data"));
      uriString = pushData.optString("uri");
    }
    catch (JSONException e)
    {
      Parse.logE("com.parse.ParsePushReceiver", "Unexpected JSONException when receiving push data: ", e);
    }
    if (uriString != null) {
          activityIntent = new Intent("android.intent.action.VIEW", Uri.parse(uriString));
        } else {
          activityIntent = new Intent(context, cls);
        }

如果你只是推送消息，uriString 将是空的而不是 null，所以context.startActivity(activityIntent); 将打开一个空的 uri 并发生异常。

要解决此问题，您可以继承 ParsePushBroadcastReceiver（感谢 @Ahmad Raza）并像这样覆盖 onPushopen：

public class Receiver extends ParsePushBroadcastReceiver {

    @Override
    protected void onPushOpen(Context context, Intent intent) {

        ParseAnalytics.trackAppOpenedInBackground(intent);

        String uriString = null;
        try {
            JSONObject pushData = new JSONObject(intent.getStringExtra("com.parse.Data"));
            uriString = pushData.optString("uri");
        } catch (JSONException e) {
            Log.v("com.parse.ParsePushReceiver", "Unexpected JSONException when receiving push data: ", e);
        }
        Class<? extends Activity> cls = getActivity(context, intent);
        Intent activityIntent;
        if (uriString != null && !uriString.isEmpty()) {
            activityIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(uriString));
        } else {
            activityIntent = new Intent(context, MainActivity.class);
        }
        activityIntent.putExtras(intent.getExtras());
        if (Build.VERSION.SDK_INT >= 16) {
            TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
            stackBuilder.addParentStack(cls);
            stackBuilder.addNextIntent(activityIntent);
            stackBuilder.startActivities();
        } else {
            activityIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            activityIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
            context.startActivity(activityIntent);
        }
    }
} 

并像这样更新清单：

<receiver
            android:name="your.package.name.Receiver"
            android:exported="false" >
            <intent-filter>
                <action android:name="com.parse.push.intent.RECEIVE" />
                <action android:name="com.parse.push.intent.DELETE" />
                <action android:name="com.parse.push.intent.OPEN" />
            </intent-filter>
        </receiver>

我希望他们在下一次更新中解决问题。
