如何自动启动Android应用程序？

I'm not sure how to autostart an android application after the android emulator completes its booting. Does anyone have any code snippets that will help me?

在android模拟器完成启动后，我不确定如何自动启动Android应用程序。有没有人有任何代码片段可以帮助我？

You have to add a manifest permission entry:

您必须添加清单权限条目：

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

(of course you should list all other permissions that your app uses).

（当然，您应该列出您的应用使用的所有其他权限）。

Then, implement BroadcastReceiver class, it should be simple and fast executable. The best approach is to set an alarm in this receiver to wake up your service (if it's not necessary to keep it running ale the time as Prahast wrote).

然后，实现BroadcastReceiver类，它应该是简单快速的可执行文件。最好的方法是在此接收器中设置一个警报以唤醒您的服务（如果没有必要像Prahast写的那样保持它的运行）。

public class BootUpReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);
    PendingIntent pi = PendingIntent.getService(context, 0, new Intent(context, MyService.class), PendingIntent.FLAG_UPDATE_CURRENT);
    am.setInexactRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + interval, interval, pi);
}}

Then, add a Receiver class to your manifest file:

然后，将Receiver类添加到清单文件中：

    <receiver android:enabled="true" android:name=".receivers.BootUpReceiver"
        android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </receiver>

Edit your AndroidManifest.xml to add RECEIVE_BOOT_COMPLETED permission

编辑AndroidManifest.xml以添加RECEIVE_BOOT_COMPLETED权限

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

Edit your AndroidManifest.xml application-part for below Permission

编辑AndroidManifest.xml应用程序部分以获得以下权限

<receiver android:enabled="true" android:name=".BootUpReceiver"
android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
<intent-filter>
    <action android:name="android.intent.action.BOOT_COMPLETED" />
    <category android:name="android.intent.category.DEFAULT" />
</intent-filter>
 </receiver>

Now write below in Activity.

现在在Activity中写下面。

public class BootUpReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
    Intent i = new Intent(context, MyActivity.class);  
    i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    context.startActivity(i);  
}
}

If by autostart you mean auto start on phone bootup then you should register a BroadcastReceiver for the BOOT_COMPLETED Intent. Android systems broadcasts that intent once boot is completed.

如果通过自动启动你的意思是手机启动时自动启动，那么你应该为BOOT_COMPLETED意图注册一个BroadcastReceiver。一旦启动完成，Android系统就会广播该意图。

Once you receive that intent you can launch a Service that can do whatever you want to do.

一旦收到该意图，您就可以启动一个可以执行任何操作的服务。

Keep note though that having a Service running all the time on the phone is generally a bad idea as it eats up system resources even when it is idle. You should launch your Service / application only when needed and then stop it when not required.

请注意，尽管在手机上一直运行服务通常是一个坏主意，因为它即使在空闲时也会占用系统资源。您应该仅在需要时启动服务/应用程序，然后在不需要时停止它。

I always get in here, for this topic. I'll put my code in here so i (or other) can use it next time. (Phew hate to search into my repository code).

对于这个话题，我总是在这里。我会把我的代码放在这里，所以我（或其他）下次可以使用它。（Phew讨厌搜索我的存储库代码）。

Add the permission:

添加权限：

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

Add receiver and service:

添加接收器和服务：

    <receiver android:enabled="true" android:name=".BootUpReceiver"
        android:permission="android.permission.RECEIVE_BOOT_COMPLETED">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </receiver>
    <service android:name="Launcher" />

Create class Launcher:

创建类Launcher：

public class Launcher extends Service {
    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        new AsyncTask<Service, Void, Service>() {

            @Override
            protected Service doInBackground(Service... params) {
                Service service = params[0];
                PackageManager pm = service.getPackageManager();
                try {
                    Intent target = pm.getLaunchIntentForPackage("your.package.id");
                    if (target != null) {
                        service.startActivity(target);
                        synchronized (this) {
                            wait(3000);
                        }
                    } else {
                        throw new ActivityNotFoundException();
                    }
                } catch (ActivityNotFoundException | InterruptedException ignored) {
                }
                return service;
            }

            @Override
            protected void onPostExecute(Service service) {
                service.stopSelf();
            }

        }.execute(this);

        return START_STICKY;
    }
}

Create class BootUpReceiver to do action after android reboot.

创建类BootUpReceiver以在android重启后执行操作。

For example launch MainActivity:

例如，启动MainActivity：

public class BootUpReceiver extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {
        Intent target = new Intent(context, MainActivity.class);  
        target.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(target);  
    }
}
