Pracuję nad aplikacją na Androida, która musi aktywować GPS.Jak włączyć GPS na Androidzie
Czytałem wiele tematów w wielu forach i odpowiedź znalazłem to:
nie jest możliwe
Ale ... „Cerberus” APP zamienia mój GPS na ... więc ... to jest możliwe!
Czy ktoś może mi w tym pomóc?
Nie jest to niemożliwe i nieodpowiednie. Nie możesz po prostu zarządzać telefonem użytkownika bez jego uprawnień.
Od Sklepie Play:
„Cerberus automatycznie włącza GPS, jeśli jest wyłączony podczas próby zlokalizowania urządzenia (tylko na Androidzie < 2.3.3) można zabezpieczyć przed nieautoryzowanym usuwanie programów - więcej informacji w konfiguracji aplikacji. "
można zrobić coś takiego:
startActivity(new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS));
Nie było exploit, który pozwolił na włączenie GPS przez aplikację bez specjalnych uprawnień. Ta luka nie istnieje już od wersji 2.3 (w większości ROM-ów). Oto kolejny post, który mówi o tym,
How can I enable or disable the GPS programmatically on Android?
„GPS włączony” to bezpieczna okolica, więc trzeba mieć pozwolenie WRITE_SECURE_SETTINGS. Jest to jednak pozwolenie na podpis, więc aplikacja nie zostanie przyznana, dopóki nie zostanie podpisana certyfikatem platformy producenta.
Prawidłowe jest wysłanie użytkownika na stronę ustawień lokalizacji i zezwolenie na włączenie GPS, jeśli chcą. np.
Intent i = new
Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(i);
może chcesz sprawdzić ten wątek
How can I enable or disable the GPS programmatically on Android?
Oto kody skopiowany z tego wątku
private void turnGPSOn(){
String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
if(!provider.contains("gps")){ //if gps is disabled
final Intent poke = new Intent();
poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
poke.setData(Uri.parse("3"));
sendBroadcast(poke);
}
}
private void turnGPSOff(){
String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
if(provider.contains("gps")){ //if gps is enabled
final Intent poke = new Intent();
poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
poke.setData(Uri.parse("3"));
sendBroadcast(poke);
}
}
ale rozwiązanie nie jest zalecane, ponieważ nie będzie dostępne le do wersji Android 2.3 supposingly> .. nie sprawdzić komentarze
if (!locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage(R.string.gps_disabled_message)
.setCancelable(false)
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(intent);
}
})
.setNegativeButton("No", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alert = builder.create();
alert.show();
}
Stwarza to ostrzeżenie i pozwala, aby przejść do ekranu ustawień i nacisnąć przycisk Wstecz, aby przyjść z powrotem do swojej aplikacji. Wykrywacz widżetów mocy nie działa zgodnie z moją wiedzą.
użyć tego kodu // turnGPSON zwany Po setcontentView (XML)
private void turnGPSOn() {
String provider = android.provider.Settings.Secure.getString(
getContentResolver(),
android.provider.Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
if (!provider.contains("gps")) { // if gps is disabled
final Intent poke = new Intent();
poke.setClassName("com.android.settings",
"com.android.settings.widget.SettingsAppWidgetProvider");
poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
poke.setData(Uri.parse("3"));
sendBroadcast(poke);
}
}**
Myślę, że mamy więcej lepszą wersję, aby umożliwić lokalizację bez otwierania ustawienia podobnie jak Google współpracuje z mapami.
Będzie wygląda następująco -
