修改下面代码,使得com.wing.MyBroadcastReceiver监听到广播android.intent.action.TEST_BROADCAST的时候启用com.modemdug.ModemDumpCollectservice,而不是com.wing.ModemDebugService package com.example.myapplication; import android.content.BroadcastReceiver; import android.content.Context; import android.content.Intent; import android.os.Handler; import android.util.Log; public class MyBroadcastReceiver extends BroadcastReceiver { private static final String TAG = "MyBroadcastReceiver"; private static final int SERVICE_STOP_DELAY = 1* 60 * 1000; // 5分钟 private Context mContext; private Handler mHandler = new Handler(); private Runnable mStopServiceRunnable = new Runnable() { @Override public void run() { stopModemDebugService(); } }; @Override public void onReceive(Context context, Intent intent) { mContext = context; // TODO Auto-generated method stub if(null == context){ return; } Log.d(TAG, "onReceive: " + intent.getAction()); if (intent.getAction().equals("android.intent.action.TEST_BROADCAST")) { startModemDebugService(); mHandler.postDelayed(mStopServiceRunnable, SERVICE_STOP_DELAY); } } private void startModemDebugService() { Intent intent = new Intent(mContext, ModemDebugService.class); Log.d(TAG,"receiver ACTION BOOT COMPLETED"); Log.d(TAG,"Globle version start ModemDebugservie"); mContext.startService(intent); Log.i(TAG,"startService ModemDebug Service"); } private void stopModemDebugService() { Intent intent = new Intent(mContext, ModemDebugService.class); Log.d(TAG,"receiver tiemr out ACTION BOOT COMPLETED"); Log.d(TAG,"Globle version end ModemDebugservie"); mContext.stopService(intent); Log.i(TAG,"StopService ModemDebug Service"); } }

请将以下代码替换为 `startModemDebugService()` 方法:
```java
private void startModemDebugService() {
Intent intent = new Intent("com.modemdug.ModemDumpCollectservice");
Log.d(TAG, "receiver ACTION TEST_BROADCAST");
Log.d(TAG, "Globle version start ModemDumpCollectservice");
mContext.startService(intent);
Log.i(TAG, "startService ModemDumpCollectservice");
}
```
这将使用 `Intent` 启动名称为 `com.modemdug.ModemDumpCollectservice` 的服务。

使用Java定义一个android APP, 1.在定义一个类里面监听广播MyBroadcastReceiver; 2.当收到MyBroadcastReceiver后,启动的service Modemdebugservice 3.同时定义一个5分钟的计时器,并在计时器5分钟结束后,停止modemdebugservice的运行; 4.定义一个属性监听Modemdebugservice,true的时候,Modemdebugservice开启,false的时候,Modemdebugservice关闭
好的,以下是一个示例代码:
```
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Handler;
import android.os.Message;
public class MyActivity extends AppCompatActivity {
private MyBroadcastReceiver myBroadcastReceiver;
private boolean isModemDebugServiceEnabled = false;
private final int STOP_MODEM_DEBUG_SERVICE = 1;
private Handler mHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
switch (msg.what) {
case STOP_MODEM_DEBUG_SERVICE:
stopModemDebugService();
break;
}
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myBroadcastReceiver = new MyBroadcastReceiver();
IntentFilter intentFilter = new IntentFilter("com.example.mybroadcastreceiver.MY_BROADCAST");
registerReceiver(myBroadcastReceiver, intentFilter);
}
private class MyBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals("com.example.mybroadcastreceiver.MY_BROADCAST")) {
startModemDebugService();
startTimer();
}
}
}
private void startModemDebugService() {
if (!isModemDebugServiceEnabled) {
isModemDebugServiceEnabled = true;
Intent intent = new Intent(this, ModemDebugService.class);
startService(intent);
}
}
private void stopModemDebugService() {
if (isModemDebugServiceEnabled) {
isModemDebugServiceEnabled = false;
Intent intent = new Intent(this, ModemDebugService.class);
stopService(intent);
}
}
private void startTimer() {
mHandler.sendEmptyMessageDelayed(STOP_MODEM_DEBUG_SERVICE, 5 * 60 * 1000); // 5 minutes
}
@Override
protected void onDestroy() {
super.onDestroy();
unregisterReceiver(myBroadcastReceiver);
stopModemDebugService();
mHandler.removeMessages(STOP_MODEM_DEBUG_SERVICE);
}
}
```
其中,MyBroadcastReceiver 监听广播 "com.example.mybroadcastreceiver.MY_BROADCAST",当接收到广播时,启动 ModemDebugService 服务,并启动一个 5 分钟的计时器,在计时器结束时停止 ModemDebugService 服务。isModemDebugServiceEnabled 属性监听 ModemDebugService 服务的状态,当为 true 时表示服务正在运行,为 false 时表示服务已经停止。在 Activity 销毁时需要停止 ModemDebugService 服务并移除计时器的消息。
那有什么办法能找到是哪个应用程序在发送这个"Intent.ACTION_CLOSE_SYSTEM_DIALOGS"广播的呢
可以通过注册一个BroadcastReceiver来监听这个广播,然后在onReceive方法中获取发送广播的应用程序的包名。例如:
```
public class MyBroadcastReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_CLOSE_SYSTEM_DIALOGS)) {
String packageName = context.getPackageName();
Log.d("BroadcastReceiver", "Broadcast received from package: " + packageName);
}
}
}
```
上面的代码中,我们监听了"Intent.ACTION_CLOSE_SYSTEM_DIALOGS"广播,当收到这个广播时,我们通过context.getPackageName()方法获取当前应用程序的包名,并打印出来。这样就能知道是哪个应用程序发送了这个广播了。
