检测您是否在Android上的Application中的主进程或远程服务进程中

我有一个应用程序,它在一个单独的进程中运行远程服务：

<service android:name=".MyService" android:process=":remote"/>

我也在使用Application类：

<application android:label="@string/app_name" android:name=".MyApplication" ...

我可以这样做吗？

public class MyApplication extends Application {

    public MyApplication() {
        if (isRemoteService()) {
            setupLog("remoteservice.log");
        } else {
            setupLog("application.log");
        }
    }

我想我可以获取进程名称并使用它来检测我是否在远程服务或主应用程序中,但我还没有找到如何获取进程名称.我可以从android.os.Process.myPID()获取PID,但这对我没什么帮助.

解决方法:

例如,如果要检查是否在主进程中,可以在应用程序中编写代码,如下所示：

public class MyApplication extends Application {
@Override
public void onCreate() {
    //...code here will be execute in every process...
    if (isMainProcess()) {
        //...code here will be execute only in main process
    }
    super.onCreate();
}

// your package name is the same with your main process name
private boolean isMainProcess() {
    return getPackageName().equals(getProcessName());
}

// you can use this method to get current process name, you will get
// name like "com.package.name"(main process name) or "com.package.name:remote"
private String getProcessName() {
    int mypid = android.os.Process.myPid();
    ActivityManager manager = (ActivityManager) getSystemService(Context.ACTIVITY_SERVICE);
    List<RunningAppProcessInfo> infos = manager.getRunningAppProcesses();
    for(RunningAppProcessInfo info : infos) {
        if (info.pid == mypid) {
            return info.processName;
        }
    }
    // may never return null
    return null;
}

}
