有没有办法直接从应用程序重启/关闭手机？
例如： 当我遇到某些特定情况时，我需要重新启动/关闭手机...

有一些选项可以阻止设备，但为什么不关机或重启？
我尝试了以下代码，但它引发了异常..
的Manifest.xml：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.schogini.PowerOff"
android:versionCode="1"
android:versionName="1.0">
<uses-permission android:name="android.permission.REBOOT" />
<uses-permission android:name="android.permission.MODIFY_PHONE_STATE" />
<uses-permission android:name="android.permission.DEVICE_POWER" />
<application android:icon="@drawable/icon" 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>
</manifest>
Java代码：
package com.schogini.PowerOff;
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.os.PowerManager;
import android.view.View;
import android.widget.Button;
public class PowerOffActivity extends Activity {
PowerManager pm;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
Button mBuyButton = (Button) findViewById(R.id.button1);
mBuyButton.setOnClickListener(new View.OnClickListener()
{
public void onClick(View v)
{
pm.reboot("null");
}
});
}
}
在LogCat中抛出异常：

不是标准的Android发行版，没有。适当的root手机通常可以访问su / reboot命令，但是对于现成的商用设备，没有：没有办法实现。

您需要使用signapk对应用程序进行签名。 jar使用以下命令：
java -jar signapk.jar platform.x509.pem platform.pk8 .apk .apk
为此你需要下载并构建android源代码并在设备上进行闪存。您可以在\ out \ host \ linux-x86 \ framework目录中找到signapk.jar。
