8. Setting Up Google Play Services
In Activity... implements ConnectionCallbacks, OnConnectionFailedListener
private GoogleApiClient mGoogleApiClient;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(Drive.API)
.addScope(Drive.SCOPE_FILE)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
}

9. Setting Up Google Play Services
In Activity...
@Override
protected void onStart() {
super.onStart();
if (!mResolvingError) { // more about this later
mGoogleApiClient.connect();
}
}
@Override
protected void onStop() {
mGoogleApiClient.disconnect();
super.onStop();
}

10. Handle connection failures
In Activity...
@Override
public void onConnected(Bundle connectionHint) { }
@Override
public void onConnectionSuspended(int cause) { }
@Override
public void onConnectionFailed(ConnectionResult result) { }

11. Handle Connection Failures
In Activity...
int REQUEST_RESOLVE_ERROR = 1001; String DIALOG_ERROR = "dialog_error"; boolean mResolvingError = false;
@Override
public void onConnectionFailed(ConnectionResult result) {
if (mResolvingError) {
return;
} else if (result.hasResolution()) {
try {
mResolvingError = true;
result.startResolutionForResult(this, REQUEST_RESOLVE_ERROR);
} catch (SendIntentException e) {
mGoogleApiClient.connect();
}
} else {
showErrorDialog(result.getErrorCode());
mResolvingError = true;
}
}

12. Handle Connection Failures
In Activity...
private void showErrorDialog(int errorCode) {
ErrorDialogFragment dialogFragment = new ErrorDialogFragment();
Bundle args = new Bundle();
args.putInt(DIALOG_ERROR, errorCode);
dialogFragment.setArguments(args);
dialogFragment.show(getSupportFragmentManager(), DIALOG_ERROR);
}
public void onDialogDismissed() { mResolvingError = false; }

13. Handle Connection Failures
In Activity...
public static class ErrorDialogFragment extends DialogFragment {
public ErrorDialogFragment() { }
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
int errorCode = this.getArguments().getInt(DIALOG_ERROR);
return GooglePlayServicesUtil.getErrorDialog(errorCode,
this.getActivity(), REQUEST_RESOLVE_ERROR);
}
@Override
public void onDismiss(DialogInterface dialog) {
((MainActivity)getActivity()).onDialogDismissed();
}
}

14. Handle Connection Failures
In Activity...
public static class ErrorDialogFragment extends DialogFragment {
public ErrorDialogFragment() { }
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
int errorCode = this.getArguments().getInt(DIALOG_ERROR);
return GooglePlayServicesUtil.getErrorDialog(errorCode,
this.getActivity(), REQUEST_RESOLVE_ERROR);
}
@Override
public void onDismiss(DialogInterface dialog) {
((MainActivity)getActivity()).onDialogDismissed();
}
}

15. Handle Connection Failures
In Activity...
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_RESOLVE_ERROR) {
mResolvingError = false;
if (resultCode == RESULT_OK) {
if (!mGoogleApiClient.isConnecting() && !mGoogleApiClient.isConnected()) {
mGoogleApiClient.connect();
}
}
}
}

16. Handle Connection Failures
In Activity...
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_RESOLVE_ERROR) {
mResolvingError = false;
if (resultCode == RESULT_OK) {
if (!mGoogleApiClient.isConnecting() && !mGoogleApiClient.isConnected()) {

2. keytool -list -v -keystore [name_key_store].keystore
Result: SHA1: DF:F0:91:5A:DF:AA … 2C:44:98:6A:0D:3D

19. Android Certificate and API Key
Create Project On: https://console.developers.google.com/project
Activate Google Maps Android API
Create a New Key for Android: [SHAI Key];[Prject Path]
Get the Google Maps API key Generated: AIz … VgHcNL7Sg

20. Configure Your Manifest
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version"
/>
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="API_KEY"
