广播接收器不包安装完成后立即工作 [英] Broadcast Receiver not working immediately after package installation

问题描述

我目前正在接收利用广播接收机的BOOT_COMPLETED操作的应用程序。接收器是静态注册在AndroidManifest.xml。

它的工作原理在下次启动安装为Android 2.2而不是3.1了。 3.1我有一次启动应用程序启动时，广播接收机得到BOOT_COMPLETED行动之前。

我怀疑，直到应用程序被启动一次东西在改变3.1，是造成我的接收器处于非活动状态。

有没有人见过这个或不知道如何制止这种行为？任何帮助将大大AP preciated。谢谢你，汤姆。

解决方案

我发现这是一个3.1政策变化。直到用户启动它的第一次一个应用程序保持安装后无效。

I am currently working on an app that receives the BOOT_COMPLETED action using a Broadcast Receiver. The receiver is statically registered in the AndroidManifest.xml.

It works on the next boot after installation for android 2.2 but not 3.1. With 3.1 I have to start the app once before the broadcast receiver gets the BOOT_COMPLETED action when booting.

I suspect that something changed in 3.1 that is causing my receiver to be inactive until the app is started once.

Has anyone ever seen this before or know how to stop this behavior? Any Help would be greatly appreciated. Thanks, Tom.

TestReceiver.java:

package com.test.receiver;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;

public class TestReceiver extends BroadcastReceiver {
  @Override
  public void onReceive(Context context, Intent intent) {
    Log.i("TestReceiver", "onReceive() was called");    
  }
}

MainActivity.java:

package com.test.receiver;
import android.app.Activity;
import android.os.Bundle;

public class MainActivity extends Activity {
  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
  }
}

解决方案

I found out this is a policy change in 3.1. An app remains inactive after installation until the user launches it for the first time.
