android静默安装与静默卸载

android5.0和6.0静默安装与卸载

android5.0使用shell命令实现静默安装和卸载

废话不多说直接上代码

//静默安装
private void installSpecific(String path) {//apk存储路径
ShellUtils.execCommand("chmod 777 " + path, false);
ShellUtils.CommandResult res = ShellUtils.execCommand("pm install -r " + pkg.getFilePath(), false);//静默安装的shell命令
ShellUtils.CommandResult result = ShellUtils.execCommand("pm uninstall " + "包名", false);//静默卸载的shell命令
if (res.result == 0 && !TextUtils.isEmpty(res.successMsg) && res.successMsg.equals("Success")) {
//安装成功
} else {
//安装失败
}
}

android6.0可以使用shell命令进行静默安装,但是静默卸载得用反射

我们直接把IPackageDeleteObserver和.IPackageInstallObserver类复制出来放到我们的工程中，注意包名要和系统文件包名android.content.pm保持一致,然后使用反射静默卸载,上代码

PackageManager pm = mContext.getPackageManager();
Method[] methods = pm != null ? pm.getClass().getDeclaredMethods() : null;
Method mDel = null;
if (methods != null && methods.length > 0) {
for (Method method : methods) {
if (method.getName().toString().equals("deletePackage")) {
mDel = method;
break;
}
}
}
if (mDel != null) {
mDel.setAccessible(true);
mDel.invoke(pm, pkg.getPackageName(), new IPackageDeleteObserver.Stub() {

@Override
public void packageDeleted(String packageName, int returnCode) throws RemoteException {
Log.i("appstore", "del apk >>" + packageName + ";code >>" + returnCode);
if (!pkg.getPackageName().equals(packageName)) {
return;
}
if (returnCode != 0) {
ToastUtils.show(mContext, pkg.getAppName() + mContext.getString(R.string
.uninstall_success));
} else {
ToastUtils.show(mContext, pkg.getAppName() + mContext.getString(R.string
.install_success));
}
}
}, 0);

添加系统权限

在系统上安装程序是需要注册权限的，在Manifest文件中加入如下语句：

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

由于然后同样是manifest文件，在节点中加入sharedUserId属性：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.slienceinstall"
android:sharedUserId="android.uid.system"          //声明为系统应用
android:versionCode="1"
android:versionName="1.0" >
... ...
<manifest/>

必须得有系统签名,应用的静默安装和卸载才能成功
