    text
    copied!<p>I am trying to handle errors for my application that uses Geocoder, but whenever i try to get the coordinates of a non-existent location my app crashes. I know this has been asked <a href="https://stackoverflow.com/questions/16733270/geocoder-not-putting-out-address">before</a> but i don't think it was resolved. Anyway i can prevent it from force closing, and just notify the user to input a correct string?</p> <p>Here is my code. a Sample string would be "qwihedhladhaw"</p> <pre><code>getCoordinatesFromString("qwihedhladhaw"); public double[] getCoordinatesFromString (String location) { Utils util = new Utils(); double coordinates[] = {0.0, 0.0}; if(util.checkIfEmptyString(location)) { this.canGetCoordinates = false; System.out.println("EMPTY STRINGS"); } else { Geocoder geocoder = new Geocoder(mContext); //geocoding List&lt;Address&gt; addressList; try { addressList = geocoder.getFromLocationName(location, 1, 14.479894, 120.970062, 14.774883, 121.061676 ); Address address = addressList.get(0); System.out.println(address); if(address.hasLatitude() &amp;&amp; address.hasLongitude()){ coordinates[0] = address.getLatitude(); coordinates[1] = address.getLongitude(); this.canGetCoordinates = true; this.isLocationValid = true; System.out.println(coordinates[0]); System.out.println(coordinates[1]); } } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } } return coordinates; } </code></pre> <p>Output logs are:</p> <pre><code> {07-30 23:12:50.291: I/System.out(26237): sDestination: 07-30 23:12:50.291: I/System.out(26237): sStart: qwert 07-30 23:12:50.526: D/AndroidRuntime(26237): Shutting down VM 07-30 23:12:50.531: W/dalvikvm(26237): threadid=1: thread exiting with uncaught exception (group=0x40c4a930) 07-30 23:12:50.566: E/AndroidRuntime(26237): FATAL EXCEPTION: main 07-30 23:12:50.566: E/AndroidRuntime(26237): java.lang.IllegalStateException: Could not execute method of the activity 07-30 23:12:50.566: E/AndroidRuntime(26237): at android.view.View$1.onClick(View.java:3599) 07-30 23:12:50.566: E/AndroidRuntime(26237): at android.view.View.performClick(View.java:4204) 07-30 23:12:50.566: E/AndroidRuntime(26237): at android.view.View$PerformClick.run(View.java:17360) 07-30 23:12:50.566: E/AndroidRuntime(26237): at android.os.Handler.handleCallback(Handler.java:725) 07-30 23:12:50.566: E/AndroidRuntime(26237): at android.os.Handler.dispatchMessage(Handler.java:92) 07-30 23:12:50.566: E/AndroidRuntime(26237): at android.os.Looper.loop(Looper.java:137) 07-30 23:12:50.566: E/AndroidRuntime(26237): at android.app.ActivityThread.main(ActivityThread.java:5233) 07-30 23:12:50.566: E/AndroidRuntime(26237): at java.lang.reflect.Method.invokeNative(Native Method) 07-30 23:12:50.566: E/AndroidRuntime(26237): at java.lang.reflect.Method.invoke(Method.java:511) 07-30 23:12:50.566: E/AndroidRuntime(26237): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:799) 07-30 23:12:50.566: E/AndroidRuntime(26237): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:566) 07-30 23:12:50.566: E/AndroidRuntime(26237): at dalvik.system.NativeStart.main(Native Method) 07-30 23:12:50.566: E/AndroidRuntime(26237): Caused by: java.lang.reflect.InvocationTargetException 07-30 23:12:50.566: E/AndroidRuntime(26237): at java.lang.reflect.Method.invokeNative(Native Method) 07-30 23:12:50.566: E/AndroidRuntime(26237): at java.lang.reflect.Method.invoke(Method.java:511) 07-30 23:12:50.566: E/AndroidRuntime(26237): at android.view.View$1.onClick(View.java:3594) 07-30 23:12:50.566: E/AndroidRuntime(26237): ... 11 more 07-30 23:12:50.566: E/AndroidRuntime(26237): Caused by: java.lang.IndexOutOfBoundsException: Invalid index 0, size is 0 07-30 23:12:50.566: E/AndroidRuntime(26237): at java.util.ArrayList.throwIndexOutOfBoundsException(ArrayList.java:251) 07-30 23:12:50.566: E/AndroidRuntime(26237): at java.util.ArrayList.get(ArrayList.java:304) 07-30 23:12:50.566: E/AndroidRuntime(26237): at com.example.otpxmlgetter.ReverseGeocode.getCoordinatesFromString(ReverseGeocode.java:33) 07-30 23:12:50.566: E/AndroidRuntime(26237): at com.example.otpxmlgetter.MainActivity.planTrip(MainActivity.java:136) 07-30 23:12:50.566: E/AndroidRuntime(26237): ... 14 more 07-30 23:17:50.721: I/Process(26237): Sending signal.
