[英]How to get the list of installed application from google play store in android?
我想要从谷歌播放或任何外部存储安装的应用程序列表,但不是预先安装的系统应用程序。
我只是使用下面的代码.....
class PInfo {
private String appname = "";
private String pname = "";
private String versionName = "";
private int versionCode = 0;
private Drawable icon;
private void prettyPrint() {
Log.v("", "*** appname = " + appname + " *** \n" + " packagename = " + pname + "\n" + " version name = " + versionName + "\n" + " version code = " + versionCode + " \n\n\n\n");
}
}
private ArrayList<PInfo> getPackages() {
ArrayList<PInfo> apps = getInstalledApps(true); /* false = no system packages */
final int max = apps.size();
int i = 0;
for (i=0; i<max; i++) {
apps.get(i).prettyPrint();
}
Log.v(TAG, "Total APPs = "+i);
return apps;
}
private ArrayList<PInfo> getInstalledApps(boolean getSysPackages) {
ArrayList<PInfo> res = new ArrayList<PInfo>();
List<PackageInfo> packs = getPackageManager().getInstalledPackages(PackageManager.GET_META_DATA);
for(int i=0;i<packs.size();i++) {
PackageInfo p = packs.get(i);
if ((!getSysPackages) && (p.versionName == null)) {
continue ;
}
PInfo newInfo = new PInfo();
newInfo.appname = p.applicationInfo.loadLabel(getPackageManager()).toString();
newInfo.pname = p.packageName;
newInfo.versionName = p.versionName;
newInfo.versionCode = p.versionCode;
newInfo.icon = p.applicationInfo.loadIcon(getPackageManager());
res.add(newInfo);
}
return res;
}
但是这段代码也给了我系统应用的信息......
任何人都知道除了已安装的系统应用程序之外如何只安装应用程序?
谢谢....
要发现您的应用程序是否是系统应用程序,您可以使用以下代码:
PackageManager pm = getPackageManager();
List<ApplicationInfo> installedApps = pm.getInstalledApplications(0);
for (ApplicationInfo aInfo: installedApps) {
if ((aInfo.flags & ApplicationInfo.FLAG_SYSTEM) != 0) {
// system application
} else {
//user application
}
}
如果您需要发现是否从市场安装了应用程序,则需要使用以下 Package方法: getInstallerPackageName
。 它将返回安装了您的应用程序的应用程序的packageName。
public class AppList extends Activity {
private ListView lView;
private ArrayList results = new ArrayList();
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
lView = (ListView) findViewById(R.id.list1);
PackageManager pm = this.getPackageManager();
Intent intent = new Intent(Intent.ACTION_MAIN, null);
intent.addCategory(Intent.CATEGORY_LAUNCHER);
List list = pm.queryIntentActivities(intent, PackageManager.PERMISSION_GRANTED);
for (ResolveInfo rInfo : list) {
results.add(rInfo.activityInfo.applicationInfo
.loadLabel(pm).toString());
Log.w("Installed Applications", rInfo.activityInfo.applicationInfo
.loadLabel(pm).toString());
}
lView.setAdapter(new ArrayAdapter(this, android.R.layout.simple_list_item_1, results));
}
}
