Google Maps issue in Android Studio project from buzztouch.com: I am having this crash when I try to load my Google Maps using the new AndroidStudio version of BT.com package. What I've done so far: 1) I was able to successfully use Google Maps with the old Eclipse package, and using Marks instructions 2) made sure I put my new SHAkey;package_name into my list of Android Applications at <a href="https://console.developers.google.com/project" target="_blank" rel="nofollow">https://console.developers.google.com/project</a> 3) Updated my AndroidManifest. xml file <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value= 4) used DiffMerge to compare the BT_screen_map.java files (Eclipse version vs the AndroidStudio version), but this was past my understanding Error from my LogCat: 03-19 15:26:10.899 7488-7488/com.ScsAndroidBuzz031915 W/ZZ?

What's on line 181? also edit the post because api key is showing.or just make a new one

line 181 from BT_screen_map.java: mapView = ((MapFragment) getFragmentManager().findFragmentById(R.id.mapView)).getMap();

Edit ----- Testing , will post back

I tested and the location map works with no problems. how did you generate the sha1 key? This is how I generate mine: http://stackoverflow.com/questions/27609442/how-to-get-the-sha1-fingerprint-certificate-in-android-studio-for-debug-mode keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android you can leave out the alias.Thats for the mac.For windows: keytool -list -v -keystore c:\users\your_user_name\.android\debug.keystore -alias androiddebugkey -storepass android -keypass android

That is same syntax I'm using, and I'm not seeing the familiar LOGCAT error if I have the wrong SHA1 key in there...it even tells you what to put in to fix it. Are you getting it to work with the new AndroidStudio Android package? I did it twice, and both had the same JAVA error. Then I did one on my self-hosted, with the Eclipse-based Android package,and the map worked. Pulling my hair out on this....any help appreciated.

Also you have to make an apk ,then install that on the device to test maps.Try making an apk and not worry about the error. See if the error still persists after you've installed the apk. Yes Im using the new android studio buzztouch project. Not the old eclipse package

Yeah, done that about 10 times across 3 projects today...burned out, try again tomorrow. Thanks CMCOFFEE for trying, really appreciate it.

Figured it out, had to do this In Android Studio, File, Project Structure, Under properties, set my Compile SDK to API 14 (was set to 21). Then under Flavors, set Target SDK to API 14 as well. Clean, Build and Run - Google maps works fine!

Nice glad you got it working

ok I have done everything you guys have done put it on a phone and it just crash when I go to use my location maps any help would be great

Hi I'm getting this error when running my app on a Samsung Galaxy s4, but not when running the same app on an HTC mini. Changing the target versions to 14 is not an option for me. Has anyone got any other suggestions?

Found a fix to my problem, it looks like a workaround for the moment. Here is the code that I changed: It's where the map is created, on the newer version of android the app is crashing using the old code, when I changed the call to getchildfragmentmanager instead of getfragmentmanager, the older version of the app crashed. So I needed to check whether the fragment was null after creating. //get reference to the map in the screen_map.xml file... // getfragmentmanager returning null on android 5.0.1 but not returning null on getchildfragmentmanager // getfragmentmanager ok on 4.2.2 but getchildfragmentmanager returns null. com.google.android.gms.maps.MapFragment myfrag = (MapFragment) getFragmentManager().findFragmentById(R.id.mapView); if (myfrag != null){ mapView = myfrag.getMap(); }else { myfrag = (MapFragment) getChildFragmentManager().findFragmentById(R.id.mapView); if(myfrag != null) mapView = myfrag.getMap(); }

That's in the manifest right

That's in the manifest right

It's in the maps plugin file. Where the map is created

getting an error from this do i need to add something Error:(188, 30) error: cannot find symbol variable getChildFragmentManager

getChildFragmentManager was introduced in api level 17 so I updated my app's minSdkVersion to this.

THIS IS WHAT I AM GETTING FOR THE LOG WINDOW /Users/briancraig/Desktop/tramp4life-for-Android-Studio-2/app/src/main/java/com/tramp4life/BT_screen_map.java:188: error: cannot find symbol myfrag = (MapFragment) (getChildFragmentManager).findFragmentById(R.id.mapView); ^ symbol: variable getChildFragmentManager location: class BT_screen_map /Users/briancraig/Desktop/tramp4life-for-Android-Studio-2/app/src/main/java/com/tramp4life/BT_screen_map.java:188: error: illegal start of type myfrag = (MapFragment) (getChildFragmentManager).findFragmentById(R.id.mapView);

It's in the maps plugin file. Where the map is created

Sorry about the extra posts Check if these support libraries are added to the grade modules file dependencies { compile 'com.android.support:support-v4:21.0.3' compile 'com.android.support:appcompat-v7:21.0.3' } If not try adding ten as dependencies

RonBo - your solution fixed my problems. TY!
