Android关机重启实现

Android通常是在长按Power键后出现弹出菜单，然后可以选择Power Off进行关机操作。代码实现在

frameworks/policies/base/phone/com/android/internal/policy/impl/PhoneWindowManager.java(mPowerLongPressRunnable)

frameworks/policies/base/phone/com/android/internal/policy/impl/GlobalActions.java

下面是个示例程序实现关机重启和恢复出厂设置，在KK上测试通过

1. Android.mk

LOCAL_PACKAGE_NAME := PowerOff

LOCAL_CERTIFICATE := platform

2. AndroidManifest.xml

package="com.***.poweroff"

android:sharedUserId="android.uid.system"

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

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

<application

android:icon="@drawable/icon"

android:label="@string/app_name" >

<activity

android:name=".PowerOff"

android:label="@string/app_name" >

<intent-filter>

<action

android:name="android.intent.action.MAIN" />

<category

android:name="android.intent.category.LAUNCHER" />

</intent-filter>

</activity>

</application>

3. PowerOff.java

ok_poweroff.setOnClickListener(new View.OnClickListener() {

public void onClick(View view) {

Log.d(TAG, "Power off starting");

Intent intent = new Intent(Intent.ACTION_REQUEST_SHUTDOWN);

intent.putExtra(Intent.EXTRA_KEY_CONFIRM, true);

intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK);

startActivity(intent);

}

});

ok_restart.setOnClickListener(new View.OnClickListener() {

public void onClick(View view) {

Log.d(TAG, "Restarting");

Intent intent = new Intent(Intent.ACTION_REBOOT);

intent.putExtra("nowait", 1);

intent.putExtra("interval", 1);

intent.putExtra("window", 0);

sendBroadcast(intent);

}

});

ok_factoryreset.setOnClickListener(new View.OnClickListener() {

public void onClick(View view) {

Log.d(TAG, "Factory reset starting");

sendBroadcast(new Intent("android.intent.action.MASTER_CLEAR"));

}

});
