java.lang.IllegalStateException on adding google places API in android

Question

I want to retrieve current place by using Google Places API but on adding it the app crashes. Here is the code of Myactivity

ChooseLanguage.java

public class ChooseLanguage extends AppCompatActivity {
ViewFlipper vf;
GoogleApiClient mGoogleapiCient;
private RadioGroup language;
private RadioButton rb;
private ProgressBar pb;
private ChooseLanguage cl;
private boolean isLanguageselected;
private String lang;
TextView tv;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_choose_language);
    cl=this;
    isLanguageselected = false;
    tv=(TextView)findViewById(R.id.tv);
    language=(RadioGroup)findViewById(R.id.radioGroup);
    pb=(ProgressBar)findViewById(R.id.progressBar);
    vf=(ViewFlipper)findViewById(R.id.viewFlipper);
    vf.setInAnimation(this,R.anim.fade_in);
    vf.setOutAnimation(this,R.anim.fade_out);
    mGoogleapiCient =  new GoogleApiClient
            .Builder( this )
            .enableAutoManage(this, 0, new GoogleApiClient.OnConnectionFailedListener() {
                @Override
                public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {

                }
            })
            .addApi( Places.GEO_DATA_API )
            .addApi( Places.PLACE_DETECTION_API )
            .build();
}
@Override
protected void onStart() {
    super.onStart();
    if( mGoogleapiCient != null )
        mGoogleapiCient.connect();
}

@Override
protected void onStop() {
    if (mGoogleapiCient != null && mGoogleapiCient.isConnected()) {
        mGoogleapiCient.disconnect();
    }
    super.onStop();
}
public void LangChosen(View view)
{
    int slctd=language.getCheckedRadioButtonId();
    rb=(RadioButton)findViewById(slctd);


    cl.lang=rb.getText().toString();
    if(cl.lang.contains("English"))
    {
        Toast.makeText(this,"Eng Chosen", Toast.LENGTH_LONG).show();
        MainActivity.getInstance().update(true);
    }
    else
    {
        Toast.makeText(this,"Hindi", Toast.LENGTH_LONG).show();
        MainActivity.getInstance().update(false);
    }
    Toast.makeText(this,"Reached", Toast.LENGTH_LONG).show();
    pb.setVisibility(View.VISIBLE);
    guessCurrentPlace();


}
private void guessCurrentPlace() {
    try {
        // location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);

        PendingResult<PlaceLikelihoodBuffer> result = Places.PlaceDetectionApi.getCurrentPlace( mGoogleapiCient, null );
        result.setResultCallback( new ResultCallback<PlaceLikelihoodBuffer>() {
            @Override
            public void onResult( PlaceLikelihoodBuffer  likelyPlaces ) {

                PlaceLikelihood placeLikelihood = likelyPlaces.get( 0 );
                String content = "";
                if( placeLikelihood != null && placeLikelihood.getPlace() != null && !TextUtils.isEmpty( placeLikelihood.getPlace().getName() ) )
                    content = "Most likely place: " + placeLikelihood.getPlace().getName() + "\n";
                if( placeLikelihood != null )
                    content += "Percent change of being there: " + (int) ( placeLikelihood.getLikelihood() * 100 ) + "%";
                tv.setText( content );

                pb.setVisibility(View.GONE);
                likelyPlaces.release();

                startActivity(new Intent(ChooseLanguage.this, MainActivity.class));
                finish();
            }
        });}

    catch (SecurityException e) {
        // lets the user know there is a problem with the gps
    }
}

}

The lines at which it is pointing are:

  PlaceLikelihood placeLikelihood = likelyPlaces.get( 0 );
result.setResultCallback( new ResultCallback<PlaceLikelihoodBuffer>() {

Answer 1

可能likelyPlaces没有条目，这可以解释为什么调用likelyPlaces.get( 0 )会引发异常的原因。

Answer 2

IllegalArgumentException was thrown to indicate that a method has been passed an illegal or inappropriate argument.

Try to implement void setPriority (int newPriority) , First the checkAccess method of this thread is called with no arguments. This may result in throwing a SecurityException. Otherwise, the priority of this thread is set to the smaller of the specified newPriority and the maximum permitted priority of the thread's thread group.
