批量安装于卸载
有尝试过在Android手机里批量安装于批量卸载你的应用程序吗,现在就简单教你怎么做,其实很简单,还有后台安装于卸载问题:
1.后台安装于卸载步骤:
首先你需要使用其Pm命令,如一下
pm install [-l] [-r] [-t] [-i INSTALLER_PACKAGE_NAME] [-s] [-f] PATH
pm uninstall [-k] PACKAGE
代码实现也很简单,使用流的方式来进行相关操作:
public static void execCommand(String... command) {
02 Process process = null;
03 try {
04 process = new ProcessBuilder().command(command).start();
05 //对于命令的执行结果我们可以通过流来读取
06 // InputStream in = process.getInputStream();
07 // OutputStream out = process.getOutputStream();
08 // InputStream err = process.getErrorStream();
09 } catch (IOException e) {
10 e.printStackTrace();
11 } finally {
12 if (process != null)
13 process.destroy();
14 }
15 }
1 execCommand("pm", "install", "-f", filePath);//安装apk,filePath为apk文件路径,如/mnt/sdcard/ApiDemos.apk
2 execCommand("pm", "uninstall", packageName);//卸载apk,packageName为包名,如com.example.android.apis
注意一下:
编译生成apk时,要在你的manifest文件下添加android:sharedUserId="android.uid.system",编译完成之后还无易做图常安装,会出现Installation error: INSTALL_FAILED_SHARED_USER_INCOMPATIBLE错误,此时,要为apk重新签名。
在android源码\build\target\product\security中找platform.pk8和platform.x509.pem两个文件,在android 编绎目录out下找到 signapk.jar 这个包(源码目录\build\tools\signapk),并把编译好的apk(如PMDemo.apk)放在同一目录下,在重新签名之前,用rar文件打开apk文件,进入META-INF目录下,将CERT.SF和CERT.RSA这两个文件删除掉,然后在命令行中执行以下命令:
1 java -jar signapk.jar platform.x509.pem platform.pk8 PMDemo.apk NewPMDemo.apk
安装前先把旧的apk卸载,这样重新签名之后的apk就可以正常安装了。
很简单吧,下面看下批量操作:
直接看代码吧:
通常情况下,android是没有提供静默方式的上层接口,我们需要在android源代码下来调用这个隐藏的接口来完成静默安装。
最重要的就是参考android系统目录下的packages/apps/PackageInstaller,
当中有两个文件 PackageInstallerActivity.java,InstallAppProgress.java ,前者就是我们通常看到的带有提示对话框的安装应用程序,后者是点确定安装后调用的intent。
现提供一个静默安装的关键类,该类在android2.2下成功编译, 其中通过循环调用接口instatllBatch则可实现批量安装
当然最后的应用程序别忘记添加权限
