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         }    }

ShellUtils工具类代码

public class ShellUtils {    public static final String COMMAND_SU = "can";    public static final String COMMAND_SH = "sh";    public static final String COMMAND_EXIT = "exit\n";    public static final String COMMAND_LINE_END = "\n";    private ShellUtils() {        throw new AssertionError();    }    /**     * check whether has root permission     *      * @return     */    public static boolean checkRootPermission() {        return execCommand("echo root", true, false).result == 0;    }    /**     * execute shell command, default return result msg     *      * @param command     *            command     * @param isRoot     *            whether need to run with root     * @return     * @see ShellUtils#execCommand(String[], boolean, boolean)     */    public static CommandResult execCommand(String command, boolean isRoot) {        return execCommand(new String[] { command }, isRoot, true);    }    /**     * execute shell commands, default return result msg     *      * @param commands     *            command list     * @param isRoot     *            whether need to run with root     * @return     * @see ShellUtils#execCommand(String[], boolean, boolean)     */    public static CommandResult execCommand(List<String> commands, boolean isRoot) {        return execCommand(commands == null ? null : commands.toArray(new String[] {}), isRoot, true);    }    /**     * execute shell commands, default return result msg     *      * @param commands     *            command array     * @param isRoot     *            whether need to run with root     * @return     * @see ShellUtils#execCommand(String[], boolean, boolean)     */    public static CommandResult execCommand(String[] commands, boolean isRoot) {        return execCommand(commands, isRoot, true);    }    /**     * execute shell command     *      * @param command     *            command     * @param isRoot     *            whether need to run with root     * @param isNeedResultMsg     *            whether need result msg     * @return     * @see ShellUtils#execCommand(String[], boolean, boolean)     */    public static CommandResult execCommand(String command, boolean isRoot, boolean isNeedResultMsg) {        return execCommand(new String[] { command }, isRoot, isNeedResultMsg);    }    /**     * execute shell commands     *      * @param commands     *            command list     * @param isRoot     *            whether need to run with root     * @param isNeedResultMsg     *            whether need result msg     * @return     * @see ShellUtils#execCommand(String[], boolean, boolean)     */    public static CommandResult execCommand(List<String> commands, boolean isRoot, boolean isNeedResultMsg) {        return execCommand(commands == null ? null : commands.toArray(new String[] {}), isRoot, isNeedResultMsg);    }    /**     * execute shell commands     *      * @param commands     *            command array     * @param isRoot     *            whether need to run with root     * @param isNeedResultMsg     *            whether need result msg     * @return <ul>     *         <li>if isNeedResultMsg is false, {@link CommandResult#successMsg}     *         is null and {@link CommandResult#errorMsg} is null.</li>     *         <li>if {@link CommandResult#result} is -1, there maybe some     *         excepiton.</li>     *         </ul>     */    public static CommandResult execCommand(String[] commands, boolean isRoot, boolean isNeedResultMsg) {        int result = -1;        if (commands == null || commands.length == 0) {            return new CommandResult(result, null, null);        }        Process process = null;        BufferedReader successResult = null;        BufferedReader errorResult = null;        StringBuilder successMsg = null;        StringBuilder errorMsg = null;        DataOutputStream os = null;        try {            process = Runtime.getRuntime().exec(isRoot ?

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
