Always 运行 Service with BroadcastReceiver for Call Tapping
Always running Service with BroadcastReceiver for Call Tapping
我的要求
我正在尝试构建一个应用程序,它会在用户从 phone 拨出电话时显示 Toast。为此,我使用 BroadcastReceiver 来点击呼叫操作和服务(总是 运行 Receiver)。一旦我开始这个 activity,它会在拨出电话启动时开始显示 toast ...一切正常。
问题
有时我也没有收到任何 Toast 操作 EVEN,这是否意味着服务会在一段时间后停止?
phone 重启后,拨出呼叫的 Toast 操作停止。直到您再次手动启动服务。
我写的代码可以吗?或者可以改进吗?
完整代码如下-
MainActivity.class
public class MainActivity extends Activity
{
CallNotifierService m_service;
boolean isBound = false;
private ServiceConnection m_serviceConnection = new ServiceConnection()
{
@Override
public void onServiceConnected(ComponentName className, IBinder service)
{
m_service = ((CallNotifierService.MyBinder)service).getService();
Toast.makeText(MainActivity.this, "Service Connected", Toast.LENGTH_LONG).show();
isBound = true;
Intent intent = new Intent(MainActivity.this, CallNotifierService.class);
startService(intent);
}
@Override
public void onServiceDisconnected(ComponentName className)
{
m_service = null;
isBound = false;
}
};
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

bindService(intent, m_serviceConnection, Context.BIND_AUTO_CREATE);
}

}
@Override

{
Log.d("service", "destroy");
this.unregisterReceiver(this.br_call);
Toast.makeText(CallNotifierService.this, "Receiver Un-Registered", Toast.LENGTH_LONG).show();
super.onDestroy();
}
@Override

@Bharat 一旦设备自动关闭,服务就会停止,所以每当您的设备重新启动时,您需要再次启动服务,那么只有您会得到吐司操作,请参考此示例代码:
BootCompleteReceiver.java
package com.example.newbootservice;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
public class BootCompleteReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Intent service = new Intent(context, AutostartService.class);
context.startService(service);
}
}
自动启动服务。java
package com.example.newbootservice;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.widget.Toast;
public class AutostartService extends Service {
@Override
public void onCreate() {
super.onCreate();
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Toast.makeText(this, "Service Started", Toast.LENGTH_LONG).show();
return Service.START_STICKY;
}
@Override
public void onDestroy() {
super.onDestroy();
Toast.makeText(this, "Service Destroy", Toast.LENGTH_LONG).show();
}
@Override
