的Andr​​oid设备上安装的应用程序拦截 [英] Interception of Installed Applications on android device

问题描述

我包名称和放大器的名单;在数据库安装的应用程序的标签，现在我想安装的应用程序和数据库拦截。假设任何应用程序从设备上删除，然后我想在数据库更改。对于我使用广播接收器，但我的code不工作。

 软件包管理系统PM = this.getPackageManager（）;
清单＆LT; ApplicationInfo＆GT; 。名单= getPackageManager（）getInstalledApplications（PackageManager.PERMISSION_GRANTED）;
对于（INT N = 0; N＆LT;则为list.size（）; N ++）{
    Apps.add（list.get（n）的.loadLabel（下午）的ToString（））;
    AppsP.add（list.get（n）的.packageName.toString（））;
    Log.w（安装的应用程序，list.get（N）.loadLabel（PM）的ToString（））;
    Log.w（安装的应用程序包，list.get（N）.packageName.toString（））;
    ...
    在其他类    公共类PackageReceiver扩展广播接收器{        @覆盖
        公共无效的onReceive（上下文的背景下，意图意图）{
            // TODO自动生成方法存根
            如果（intent.getAction（）。equalsIgnoreCase（Intent.ACTION_PACKAGE_ADDED））{
                。字符串added_pa​​ckage = intent.getData（）的toString（）;
                Log.i（PackageReceiver，包新增=+ added_pa​​ckage）;            }否则如果（intent.getAction（）。equalsIgnoreCase（Intent.ACTION_PACKAGE_REMOVED））{
                。字符串removed_pa​​ckage = intent.getData（）的toString（）;
                MyDBHelper DB =新MyDBHelper（背景）;
                Log.i（PackageReceiver，包删除=+ removed_pa​​ckage）;
                DB.open（）;
                DB.deleteStmt = DB.db.compileStatement（QueryManager.ApplicationDelete）;
                DB.deleteStmt.bindString（1，removed_pa​​ckage）;
                DB.close（）;            }
 

任何帮助??

解决方案

  intentAPP.addAction（Intent.ACTION_PACKAGE_ADDED）;
            intentAPP.addAction（Intent.ACTION_PACKAGE_CHANGED）;
            intentAPP.addAction（Intent.ACTION_PACKAGE_DATA_CLEARED）;

                    DB.insertStmt.bindString（4，假）;
                    DB.insertStmt.executeInsert（）;                }//添加封装的通知
如果（intent.getAction（）。equalsIgnoreCase（Intent.ACTION_PACKAGE_ADDED））{
            。字符串added_pa​​ckage = intent.getData（）的toString（）;
            Log.i（PackageReceiver，包新增=+ added_pa​​ckage）;
            意图Intent_add =新的Intent（）;
            Intent_add.setClass（背景下，ServiceAppsAdd.class）;
            Intent_add.putExtra（PACKAGE_NAME，added_pa​​ckage.substring（8））;

I got the list of Package name & Label of installed application in database, Now I want to interception with installed application and database. Suppose any application delete from device then I want changes in Database. for that i am using broadcast receiver but my code not works.

PackageManager pm = this.getPackageManager();
List < ApplicationInfo > list = getPackageManager().getInstalledApplications(PackageManager.PERMISSION_GRANTED);
for (int n = 0; n < list.size(); n++) {
    Apps.add(list.get(n).loadLabel(pm).toString());
    AppsP.add(list.get(n).packageName.toString());
    Log.w("Installed Applications", list.get(n).loadLabel(pm).toString());
    Log.w("Installed Applications Package", list.get(n).packageName.toString());


    ...
    In other class

    public class PackageReceiver extends BroadcastReceiver {

        @Override
        public void onReceive(Context context, Intent intent) {
            // TODO Auto-generated method stub
            if (intent.getAction().equalsIgnoreCase(Intent.ACTION_PACKAGE_ADDED)) {
                String added_package = intent.getData().toString();
                Log.i("PackageReceiver", "Package Added = " + added_package);

            } else if (intent.getAction().equalsIgnoreCase(Intent.ACTION_PACKAGE_REMOVED)) {
                String removed_package = intent.getData().toString();
                MyDBHelper DB = new MyDBHelper(context);
                Log.i("PackageReceiver", "Package removed = " + removed_package);
                DB.open();
                DB.deleteStmt = DB.db.compileStatement(QueryManager.ApplicationDelete);
                DB.deleteStmt.bindString(1, removed_package);
                DB.close();

            }

any help??

解决方案

    intentAPP.addAction(Intent.ACTION_PACKAGE_ADDED);
            intentAPP.addAction(Intent.ACTION_PACKAGE_CHANGED);
            intentAPP.addAction(Intent.ACTION_PACKAGE_DATA_CLEARED);
            intentAPP.addAction(Intent.ACTION_PACKAGE_INSTALL);
            intentAPP.addAction(Intent.ACTION_PACKAGE_REMOVED);
            intentAPP.addAction(Intent.ACTION_PACKAGE_REPLACED);
            intentAPP.addAction(Intent.ACTION_PACKAGE_RESTARTED);

//for storing list in db

    for (int i = 0; i < AppsP.size() && i < Apps.size(); i++) {

                    DB.insertStmt.bindString(1, URLDecoder.decode(AppsP.get(i)));
                    DB.insertStmt.bindString(2, URLDecoder.decode(Apps.get(i)));
                    DB.insertStmt.bindString(3, 1 + "");
                    DB.insertStmt.bindString(4, "false");
                    DB.insertStmt.executeInsert();

                }

//adding package notification
if (intent.getAction().equalsIgnoreCase(Intent.ACTION_PACKAGE_ADDED)) {
            String added_package = intent.getData().toString();
            Log.i("PackageReceiver", "Package Added = " + added_package);
            Intent Intent_add = new Intent();
            Intent_add.setClass(context, ServiceAppsAdd.class);
            Intent_add.putExtra("Package_Name", added_package.substring(8));
            Intent_add.putExtra("Status", status_new);
            context.startService(Intent_add);
