获取所有应用及相关信息
方法1:ResolveInfo
获取全部应用: PackageManager packageManager = getPackageManager(); Intent mIntent = new Intent(Intent.ACTION_MAIN, null); mIntent.addCategory(Intent.CATEGORY_LAUNCHER); List<ResolveInfo> listAllApps = packageManager.queryIntentActivities(mIntent, 0); 判断是否系统应用: ResolveInfo appInfo = listAllApps.get(position); String pkgName = appInfo.activityInfo.packageName;//获取包名 //根据包名获取PackageInfo mPackageInfo;(需要处理异常) mPackageInfo = mContext.getPackageManager().getPackageInfo(pkgName, 0); if ((mPackageInfo.applicationInfo.flags & ApplicationInfo.FLAG_SYSTEM) <= 0) { //第三方应用 } else { //系统应用 } 获取相关信息: ResolveInfo mResolveInfo ; 获取包名: mResolveInfo.activityInfo.packageName; 获取icon: mResolveInfo.loadIcon(packageManager); 获取应用名: mResolveInfo.loadLabel(packageManager).toString();
方法2:PackageInfo
获取全部应用: PackageManager packageManager = this.getPackageManager(); List<PackageInfo> packageInfoList = packageInfoList .getInstalledPackages(0); 判断是否系统应用: List<PackageInfo> apps = new ArrayList<PackageInfo>(); for (int i = 0; i < packageInfoList.size(); i++) { PackageInfo pak = (PackageInfo)packageInfoList.get(i); //判断是否为系统预装的应用 if ((pak.applicationInfo.flags & pak.applicationInfo.FLAG_SYSTEM) <= 0) { // 第三方应用 apps.add(pak); } else { //系统应用 } } 获取相关信息: PackageInfo mPackageInfo; 获取包名: mPackageInfo.packageName 获取icon: mPackageInfo.getApplicationIcon(applicationInfo); 获取应用名: mPackageInfo.getApplicationLabel(applicationInfo); 获取使用权限: mPackageInfo.getPackageInfo(packageName,PackageManager.GET_PERMISSIONS).requestedPermissions;
监听应用的安装和卸载:
//////////////注册广播,监听安装和卸载 public void onReceive(Context context, Intent intent) { if (intent.getAction().equals("android.intent.action.PACKAGE_ADDED")) { //获取安装应用的包名 String packageName = intent.getDataString(); } else if (intent.getAction().equals("android.intent.action.PACKAGE_REMOVED")) { //获取卸载应用的包名 String packageName = intent.getDataString(); } }
