Android在代码中实现重启(reboot) ,直接上代码: public void rebootAction(){
new AlertDialog.Builder(this)
.setTitle("Warning")
.setMessage("Sure to reboot?")
.setNegativeButton("Cancel", null)
.setPositiveButton("OK", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
String cmd = "su -c reboot";
try {
Runtime.getRuntime().exec(cmd);
} catch (Exception e){
Toast.makeText(getApplicationContext(), "Error! Fail to reboot.", Toast.LENGTH_SHORT).show();
}
}
})
.show();
}还有一种方法,但是需要系统级程序才可以使用,否则会提示权限不够。 try {
Intent intent = new Intent(Intent.ACTION_REBOOT);
intent.putExtra("nowait", 1);
intent.putExtra("interval", 1);
intent.putExtra("window", 0);
this.sendBroadcast(intent);
} catch (Exception e){
new AlertDialog.Builder(this).setTitle("Error").setMessage(e.getMessage()).setPositiveButton("OK", null).show();
}在普通app中调用会报错:java.lang.SecurityException: Permission Denial: not allowed to send broadcast android.intent.action.REBOOT from pid=11892, uid=10146更多Android相关信息见Android 专题页面 http://www.linuxidc.com/topicnews.aspx?tid=11
