如何以编程方式获取 Android 7.0 运行 设备中已安装的浏览器应用程序列表?
How to get the list of installed Browser Apps in an Android 7.0 running devices programmatically?
在 Android 7.0 之前,我能够检索已安装的浏览器类型应用程序的列表及其包名称。然后,我升级到 Android 7.0,我只能检索三星的互联网浏览器,但不能检索其他浏览器类型的应用程序,例如 Chrome .
设备三星标签 A
这是代码:
public static List<String> getListOfBrowser(Context context) {
List<String> browserPackageName = new ArrayList<String>();
try {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse("http://www.google.com"));
PackageManager pm = context.getPackageManager();
List<ResolveInfo> browserList = pm.queryIntentActivities(intent, 0);
for (ResolveInfo info : browserList) {
browserPackageName.add(info.activityInfo.packageName);
Log.e("BrowserList Info ",info.activityInfo.packageName+" total browser"+browserList.size());
}
} catch (Exception e) {
e.printStackTrace();
Log.e("BrowserList Info ",e.getMessage());
}
return browserPackageName;
}
代码看起来不错。但是你应该使用 PackageManager.MATCH_DEFAULT_ONLY
标志 -
pm.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
而不是
pm.queryIntentActivities(intent, 0);
如果Android API等级>=23,那么你可以这样做:
List<ResolveInfo> browserList;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.MARSHMALLOW) {
// gets all
browserList = pm.queryIntentActivities(intent, PackageManager.MATCH_ALL);
// only the defaults
browserList = pm.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
} else {
browserList = pm.queryIntentActivities(intent, 0);
}
