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
