以下两种方法都试过了，可以用！
首先在清单文件添加权限：<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
然后创建一个广播类，代码如下：package com.example.administrator.newapp;
import android.content.BroadcastReceiver;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import com.example.administrator.newapp.MainActivity;
/**
* Created by Administrator on 2016/12/1.
*/
public class LocationLoggerServiceManager extends BroadcastReceiver {
public static final String TAG = "customTag";
@Override
public void onReceive(Context context, Intent intent) {
if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) {
ComponentName comp = new ComponentName(context.getPackageName(), MainActivity.class.getName());
context.startActivity(new Intent().setComponent(comp).addFlags(Intent.FLAG_ACTIVITY_NEW_TASK));
} else {
Log.e(TAG, "Received unexpected intent " + intent.toString());
}
}
}
第三步在清单文件写： <receiver
android:name=".LocationLoggerServiceManager"
android:enabled="true"
android:exported="false"
android:label="LocationLoggerServiceManager">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
好了，重新开机，就可以了！
第二种方法：和第一种差不多：
https://zhidao.baidu.com/question/875702278060777652.html
首先：public class BootupReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
//better delay some time.
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Intent i = new Intent(context, BootupDemoActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
}
} 然后在Manifest文件中定义该Broadcast Receiver
<receiver android:name=”.BootupReceiver” android:enabled=”true”
android:permission=”android.permission.RECEIVE_BOOT_COMPLETED”>
<intent-filter>
<action android:name=”android.intent.action.BOOT_COMPLETED”></action>
<category android:name=”android.intent.category.DEFAULT” />
</intent-filter>
</receiver>
3. 加上所需权限
<uses-permission android:name=”android.permission.RECEIVE_BOOT_COMPLETED” />
这些，但手机重启示会自动运行你的应用。 不过此时你的应用可能会被屏幕锁定挡住。解除屏幕锁定后可以看到你运行的应用。
如果想用户一开机就看到你的应用，可以使用代码就屏幕锁去除，方法如下：
1. 在Activity的onCreate事件处理中添加下面代码
[java]
KeyguardManager keyguardManager
= (KeyguardManager)getSystemService(KEYGUARD_SERVICE);
KeyguardLock lock = keyguardManager.newKeyguardLock(KEYGUARD_SERVICE);
lock.disableKeyguard();
KeyguardManager keyguardManager
= (KeyguardManager)getSystemService(KEYGUARD_SERVICE);
KeyguardLock lock = keyguardManager.newKeyguardLock(KEYGUARD_SERVICE);
lock.disableKeyguard();
2. 在Manifest文件中添加所需权限
<uses-permission android:name=”android.permission.DISABLE_KEYGUARD” />
