打开Parse推送通知时出现exception
我设置parsing推Android SDK 1.7.0，并可以收到推无任何问题。 但是，当打开推送通知我的应用程序崩溃，以下例外：
android.content.ActivityNotFoundException：没有发现处理意图的活动{act = android.intent.action.VIEW dat = flg = 0x1000c000（有额外）}
我也试过用getActivity() ParsePushBroadcastReceiver ，总是返回主活动类，结果相同。 以下是完整的堆栈跟踪：

花了几个小时后。 find一个解决scheme：实现你的接收器并扩展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>
快乐编码！
这个exception的原因是当ParsePushBroadcastReceiver想在这个代码中打开推送消息中的空uri时：
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); }
如果你只是推送一个消息， uriString将是空的不是null，所以context.startActivity(activityIntent); 会打开一个空的uri，并发生exception。
为了解决这个问题，你可以ParsePushBroadcastReceiver （感谢@Ahmad Raza）并覆盖onPushopen像这样：
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); } } }
并更新Manifest像这样：
<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>
我希望他们在下次更新中解决这个问题。
