如何获取在Android中以编程方式使用位置的应用列表？

Question

I'm developing an app on Android OS.

I need a method that returns the list of apps that rely on location services/GPS

You can use the code (from here ) to get list of permissions of installed apps on the device. Then search for the required permissions about location services like ACCESS_FINE_LOCATION. Your code would be something like this:

PackageManager pm = getPackageManager();
List packages = pm.getInstalledApplications(PackageManager.GET_META_DATA);
for (ApplicationInfo applicationInfo : packages) {
    Log.d("test", "App: " + applicationInfo.name + " Package: " + applicationInfo.packageName);
    try {
        PackageInfo packageInfo = pm.getPackageInfo(applicationInfo.packageName, PackageManager.GET_PERMISSIONS);
        //Get Permissions
        String[] requestedPermissions = packageInfo.requestedPermissions;
        if(requestedPermissions != null) {
            for (int i = 0; i < requestedPermissions.length; i++) {
                Log.d("test", requestedPermissions[i]);

                //////////////////////////////////////
                //////////////////////////////////////
                // Look for the desired permission here
                //////////////////////////////////////
                //////////////////////////////////////
            }
        }
    } catch (NameNotFoundException e) {
        e.printStackTrace();
    }
}

And to do so, you need the following in your manifest:

<uses-permission android:name="android.permission.GET_TASKS"/>
