1.在AndroidManifest.xml文件的manifest標籤中加入一條android:sharedUserId="android.uid.system"android
01 |
< manifest xmlns:android = "http://schemas.android.com/apk/res/android" |
02 |
package = "com.ipanel.update" |
03 |
android:versionCode = "1" |
04 |
android:versionName = "1.0" |
05 |
android:sharedUserId = "android.uid.system" > |
08 |
android:minSdkVersion = "9" |
09 |
android:targetSdkVersion = "15" /> |
10 |
< uses-permission android:name = "android.permission.INTERNET" /> |
11 |
< uses-permission android:name = "android.permission.WRITE_EXTERNAL_STORAGE" /> |
12 |
< uses-permission android:name = "android.permission.MODIFY_AUDIO_SETTINGS" /> |
15 |
android:icon = "@drawable/ic_launcher" |
16 |
android:label = "@string/app_name" |
17 |
android:theme = "@style/AppTheme" > |
19 |
android:name = ".MainActivity" |
20 |
android:label = "@string/title_activity_main" > |
22 |
< action android:name = "android.intent.action.MAIN" /> |
24 |
< category android:name = "android.intent.category.LAUNCHER" /> |
2.在MainActivity中,有如下2種方式實現:web
1 |
/*Intent reboot = new Intent(Intent.ACTION_REBOOT); |
2 |
reboot.putExtra("nowait", 1); |
3 |
reboot.putExtra("interval", 1); |
4 |
reboot.putExtra("window", 0); |
5 |
sendBroadcast(reboot); */ |
6 |
PowerManager pManager=(PowerManager) getSystemService(Context.POWER_SERVICE); |
整個代碼:app
01 |
package com.demo.reboot; |
04 |
import java.io.IOException; |
05 |
import java.io.InputStream; |
07 |
import android.app.Activity; |
08 |
import android.app.AlertDialog; |
09 |
import android.content.Context; |
10 |
import android.content.DialogInterface; |
11 |
import android.content.Intent; |
12 |
import android.os.Bundle; |
13 |
import android.os.PowerManager; |
14 |
import android.view.View; |
15 |
import android.view.View.OnClickListener; |
16 |
import android.widget.Button; |
18 |
public class MainActivity extends Activity { |
21 |
public void onCreate(Bundle savedInstanceState) { |
22 |
super .onCreate(savedInstanceState); |
23 |
setContentView(R.layout.activity_main); |
25 |
Button rebootBtn = (Button) findViewById(R.id.button2); |
26 |
rebootBtn.setOnClickListener( new OnClickListener() { |
28 |
public void onClick(View v) { |
29 |
new AlertDialog.Builder(MainActivity. this ) |
32 |
.setPositiveButton( "重啓" , new DialogInterface.OnClickListener() { |
34 |
public void onClick(DialogInterface dialog, int which) { |
38 |
str = runCmd("reboot", "/system/bin"); |
39 |
} catch (IOException e) { |
42 |
/*Intent reboot = new Intent(Intent.ACTION_REBOOT); |
43 |
reboot.putExtra("nowait", 1); |
44 |
reboot.putExtra("interval", 1); |
45 |
reboot.putExtra("window", 0); |
46 |
sendBroadcast(reboot); */ |
47 |
PowerManager pManager=(PowerManager) getSystemService(Context.POWER_SERVICE); |
48 |
pManager.reboot( "重啓" ); |
49 |
System.out.println( "execute cmd--> reboot\n" + "重啓" ); |
52 |
.setNegativeButton( "取消" , new DialogInterface.OnClickListener() { |
54 |
public void onClick(DialogInterface dialog, int which) { |
3.給apk簽名
簽名方法:ide
loop android簽名機制(2)——如何簽名工具
1>添加權限oop
在AndroidManifest.xml文件下添加android:sharedUserId="android.uid.system" 。ui
2>在Eclipse中導出無簽名的應用文件this
在工程中:右鍵->Android Tools -> Export Unsigned Application Package導出應用
3>找出系統簽名密鑰
系統密鑰爲: platform.pk8和platform.x509.pem
路徑: build\target\product\security
4>找出系統簽名工具
工具爲:signApk.jar
路徑:/out/host/linux-x86/framework/ signApk.jar
5>開始簽名
將第二、三、4步找到的無簽名應用、platform.pk八、platform.x509.pem和signApk.jar放到同一文件夾下如F:\sign。
打開 dos 操做界面,定們到F:\sign,輸入命令:
java -jar signapk.jar platform.x509.pem platform.pk8 **.apk ***.apk
(**.apk 爲未簽名應用 ***.apk 爲簽名以後應用)
注:以前在評論裏有錯誤的說過這個簽名工具是通用的,這裏糾正下。編譯導出的apk,要安裝到那個版本的系統,就去那源碼裏找對應的簽名工具,並非各個版本通用
