本文详细介绍了如何在Android应用中实现静默更新和自启动功能，包括使用root权限安装应用、监听应用安装与卸载的广播、以及添加必要的权限。同时，提供了具体的代码示例和步骤说明。

采用获取root方式安装安装包，并通过广播监听安装包的安装卸载。

1.注册广播接收器

/**
 * 监听安装包安装卸载的广播接收器
 */
public class UpdateReceiver extends BroadcastReceiver {

    public static final String APK_FILE_PATH = Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator + "Download" + File.separator + "test.apk";

    @Override
    public void onReceive(Context context, Intent intent) {
        if (Intent.ACTION_PACKAGE_REPLACED.equals(intent.getAction())) {
            Log.i("install", "安装了完成:" + "包名的程序");
            Intent intent1 = context.getPackageManager().getLaunchIntentForPackage("com.example.joe");
            context.startActivity(intent1);
            File file = new File(APK_FILE_PATH);
            if (file.exists() && file.isFile()) {
                Log.i("install", "删除了文件:" + APK_FILE_PATH);
                file.delete();
            } else {
                Log.i("install", "文件不存在:" + APK_FILE_PATH);
            }
        }
        //接收安装广播
        if (Intent.ACTION_PACKAGE_ADDED.equals(intent.getAction())) {
            String packageName = intent.getDataString();
            Log.e("install", "安装了:" + packageName + "包名的程序");

        }
        //接收卸载广播
        if (Intent.ACTION_PACKAGE_REMOVED.equals(intent.getAction())) {
            String packageName = intent.getDataString();
            Log.e("install", "卸载了:" + packageName + "包名的程序");
        }
    }
}


 <!--静默更新、自启动-->
 <receiver android:name=".UpdateReceiver">
     <intent-filter>
           <action android:name="android.intent.action.PACKAGE_REPLACED" />
           <action android:name="android.intent.action.PACKAGE_ADDED" />
           <action android:name="android.intent.action.PACKAGE_CHANGED" />
          	<action android:name="android.intent.action.PACKAGE_REPLACED" />
            <action android:name="android.intent.action.PACKAGE_REMOVED" />
	        <data android:scheme="package" />
     </intent-filter>
 </receiver>

添加权限：

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

    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
    <uses-permission android:name="android.permission.RESTART_PACKAGES" />
    <uses-permission android:name="android.permission.MOUNT_UNMOUNT_FILESYSTEMS" />
    <uses-permission android:name="android.permission.BROADCAST_PACKAGE_REPLACED" />
    <uses-permission android:name="android.permission.BROADCAST_PACKAGE_REMOVED" />
    <uses-permission android:name="android.permission.INSTALL_PACKAGES" />
    <uses-permission android:name="android.permission.DELETE_PACKAGES" />
    <uses-permission android:name="android.permission.CLEAR_APP_USER_DATA" />
    <uses-permission android:name="android.permission.CLEAR_APP_CACHE" />
    <uses-permission android:name="android.permission.WRITE_MEDIA_STORAGE" />

2.安装工具类

public class RootUtils {
    public static final String[] SU_BINARY_DIRS = {
            "/system/bin",
            "/system/sbin",
            "/system/xbin",
            "/vendor/bin",
            "/sbin"
    };

    /**
     * 检查设备是否root
     *
     * @return
     */
    public static boolean checkRoot() {
        boolean isRoot = false;
        try {
            for (String dir : SU_BINARY_DIRS) {
                File su = new File(dir, "su");
                if (su.exists()) {
                    isRoot = true;
                    break;
                }
            }
        } catch (Exception e) {
        }
        return isRoot;
    }

    private static void closeIO(Closeable closeable) {
        try {
            if (closeable != null) {
                closeable.close();
            }
        } catch (Exception e) {
        }
    }

    /**
     * 运行root命令
     *
     * @return
     */
    public static boolean runRootCmd(String cmd) {
        boolean grandted;
        DataOutputStream outputStream = null;
        BufferedReader reader = null;
        try {
            Process process = Runtime.getRuntime().exec("su");
            outputStream = new DataOutputStream(process.getOutputStream());
            outputStream.writeBytes(cmd + "\n");
            outputStream.writeBytes("exit\n");
            outputStream.flush();
            process.waitFor();
            reader = new BufferedReader(new InputStreamReader(process.getErrorStream()));
            grandted = true;

            String msg = reader.readLine();
            if (msg != null) {
                Log.v(RootUtils.class.getSimpleName(), msg);
            }
        } catch (Exception e) {
            e.printStackTrace();
            grandted = false;

            closeIO(outputStream);
            closeIO(reader);
        }
        return grandted;
    }

    public static boolean installPkg(String apkPath) {
        return runRootCmd("pm install -r " + apkPath);
    }

    /**
     * 为app申请root权限
     *
     * @param context
     * @return
     */
    public static boolean grantRoot(Context context) {
        return runRootCmd("chmod 777 "+ context.getPackageCodePath());
    }
}

 private void installApk(File apk) {
        if (apk != null & apk.exists()) {
            if (RootUtils.checkRoot()) {
                RootUtils.installPkg(apk.getAbsolutePath());
            }
        }
    }
