How to enable/disable gps and mobile data in android programmatically?
提问by Taimur Ayaz
I want my application to be able to enable/disable gps and mobile data programmatically as there are many apps like tasker, profile flow, lookout extra which can do this so I searched for it but not found any useful example I found the following code but they didn't work.
我希望我的应用程序能够以编程方式启用/禁用 gps 和移动数据，因为有许多应用程序，如 tasker、profile flow、lookout extra 可以做到这一点，所以我搜索了它但没有找到任何有用的例子我找到了以下代码但是他们没有工作。
private void setMobileDataEnabled(Context context, boolean enabled) {
final ConnectivityManager conman = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
final Class conmanClass = Class.forName(conman.getClass().getName());
final Field iConnectivityManagerField = conmanClass.getDeclaredField("mService");
iConnectivityManagerField.setAccessible(true);
final Object iConnectivityManager = iConnectivityManagerField.get(conman);
final Class iConnectivityManagerClass = Class.forName(iConnectivityManager.getClass().getName());
final Method setMobileDataEnabledMethod = iConnectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE);
setMobileDataEnabledMethod.setAccessible(true);
setMobileDataEnabledMethod.invoke(iConnectivityManager, enabled);
}
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);
}
}

Fortunately, this is not possible, for obvious privacy reasons. While there were some hacks, like the one in your question, that used to work, those security flaws have since been fixed.
幸运的是，出于明显的隐私原因，这是不可能的。虽然有一些黑客，比如你问题中的那个，曾经有效，但这些安全漏洞已经得到修复。

因为有很多应用程序，如 tasker、profile flow、lookout extra 可以做到这一点
You are welcome to supply evidence that any of those apps can do this on modern versions of Android.
欢迎您提供证据，证明这些应用程序中的任何一个都可以在现代版本的 Android 上执行此操作。

Try this for turning on gps
试试这个来打开 GPS
public void turnGPSOn()
{
Intent intent = new Intent("android.location.GPS_ENABLED_CHANGE");
intent.putExtra("enabled", true);
this.ctx.sendBroadcast(intent);
String provider = Settings.Secure.getString(ctx.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"));
this.ctx.sendBroadcast(poke);
}
}
for turning off gps,
用于关闭 GPS，
public void turnGPSOff()
{
String provider = Settings.Secure.getString(ctx.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"));
this.ctx.sendBroadcast(poke);
}
}
For mobile data, did you added the permission in manifest? If not try adding and check it.
对于移动数据，您是否在清单中添加了权限？如果没有尝试添加并检查它。
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE"/>
Let me know if everything worked.
如果一切正常，请告诉我。
