测试平台

Platform: RK3399
OS: Android 7.1.1

需求

静默安装应用

解决方案

实现静默安装应用的话需要系统权限:
在AndroidManifest.xml中添加android:sharedUserId=“android.uid.system”.
使用系统签名文件(platform.pk8、platform.x509.pem,签名文件位于build/target/product/security/目录下)对apk进行签名

在AndroidManifest.xml添加相应需要的权限

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

添加函数代码，调用函数进行应用安装

int result = installSilent("com.firefly.testslinet","/mnt/sdcard/123.apk");

前面包名是你实现静默安装的应用的包名，比如我的是testslinet 应用来静默安装/sdcrad/123.apk.那么就是 installSilent(“com.firefly.testslinet”,"/mnt/sdcard/123.apk");

     /** 
      * 静默安装
      * @param packageName　 　调用installSilent函数的应用包名
      * @param filePath 　　　　静默安装应用的apk路径
      * @return 0 安装成功
      * 　　　　　　　 1 文件不存在
      * 　　　　　　　 2 安装失败 
      */  
     public static int installSilent(String packageName,String filePath) {  
             File file = new File(filePath);  
             if (filePath == null || filePath.length() == 0 || file == null || file.length() <= 0 || !file.exists() || !file.isFile()) {  
                     return 1;  
             }  
             //pm install -i 包名 --user 0 apkpath
             String[] args = { "pm", "install","-i",packageName,"--user","0", "-r", filePath };  
             ProcessBuilder processBuilder = new ProcessBuilder(args);  
             Process process = null;  
             BufferedReader successResult = null;  
             BufferedReader errorResult = null;  
             StringBuilder successMsg = new StringBuilder();  
             StringBuilder errorMsg = new StringBuilder();  
             int result;  
             try {  
                     process = processBuilder.start();  
                     successResult = new BufferedReader(new InputStreamReader(process.getInputStream()));  
                     errorResult = new BufferedReader(new InputStreamReader(process.getErrorStream()));  
                     String s; 
                     while ((s = successResult.readLine()) != null) {  
                             successMsg.append(s);
                             Log.d("installSilent", "while successMsg s:" + s);  
                     } 
                     while ((s = errorResult.readLine()) != null) {  
                             errorMsg.append(s);  
                             Log.d("installSilent", "while errorMsg s:" + s);  
                     }  
             } catch (IOException e) {  
                     e.printStackTrace();  
             } catch (Exception e) {  
                     e.printStackTrace();  
             } finally {  
                     try {  
                             if (successResult != null) {  
                                     successResult.close();  
                             }  
                             if (errorResult != null) {  
                                     errorResult.close();  
                             }  
                     } catch (IOException e) {  
                             e.printStackTrace();  
                     }  
                     if (process != null) {  
                             process.destroy();  
                     }  
             }  

             if (successMsg.toString().contains("Success") || successMsg.toString().contains("success")) {  
                     result = 0;  
             } else {  
                     result = 2;  
             }  
             Log.d("installSilent", "successMsg:" + successMsg + ", ErrorMsg:" + errorMsg);  
             return result;  
     }

有客户提出应用静默安装升级本身后希望可以自启动，下面提供自启动方案:

// AndroidManifest.xml
        <receiver android:name="com.example.testfile.BootBroadcastReceiver" >
            <intent-filter>
                <action android:name="android.intent.action.PACKAGE_ADDED" />
                <action android:name="android.intent.action.PACKAGE_REPLACED" />
                <action android:name="android.intent.action.PACKAGE_REMOVED" />
                <data android:scheme="package" />
            </intent-filter>
        </receiver>


//BootBroadcastReceiver.java
package com.example.testfile;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.Toast;

public class BootBroadcastReceiver extends BroadcastReceiver{
	private static final String TAG = "sjft";

	public static final String EXTRA_VOLUME_STATE =
			"android.os.storage.extra.VOLUME_STATE";

	public static final int STATE_UNMOUNTED = 0;
	public static final int STATE_CHECKING = 1;
	public static final int STATE_MOUNTED = 2;
	public static final int STATE_MOUNTED_READ_ONLY = 3;
	public static final int STATE_FORMATTING = 4;
	public static final int STATE_EJECTING = 5;
	public static final int STATE_UNMOUNTABLE = 6;
	public static final int STATE_REMOVED = 7;
	public static final int STATE_BAD_REMOVAL = 8;

	@Override
	public void onReceive(Context context, Intent intent) {
		// TODO Auto-generated method stub
		String action = intent.getAction();
		if (action.equals("android.intent.action.PACKAGE_REPLACED")){
			String packageName = intent.getData().getSchemeSpecificPart();
			Log.v(TAG,"BootBroadcastReceiver packageName:"+packageName);
			if(context.getPackageName().equals(packageName)){
				Intent launchIntent = new Intent(context, MainActivity.class);//重新启动应用
				//此处如果不想写死启动的Activity，也可以通过如下方法获取默认的启动Activity
				//Intent launchIntent = context.getPackageManager().getLaunchIntentForPackage(packageName);
				intent2.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
				context.startActivity(launchIntent);
			}
		}
	}
