我试图利用Twitter登录我的小 Android应用程序时遇到问题,它一直给出错误说无法找到符号’Twitter’我在网上搜索了几个解决方案,包括下面的这个,但没有找到任何可能的解决方案.

Twitter Fabric – Cannot Resolve Symbol

我已经清理,重建,甚至重新启动我的Android工作室,尝试重新同步Gradle但尚无解决方案.

这是我的Build.Gradle(Project)

@H_404_8@buildscript { repositories { mavenCentral() maven { url 'https://maven.fabric.io/public' } jcenter() } dependencies { classpath 'com.android.tools.build:gradle:1.2.3' // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } } allprojects { repositories { jcenter() maven { url 'https://maven.fabric.io/public' } } }

这是我的Build.Gradle(应用程序)

@H_404_8@apply plugin: 'com.android.application' android { compileSdkVersion 22 buildToolsVersion "22.0.1" repositories { mavenCentral() maven { url 'https://maven.fabric.io/public' } } defaultConfig { applicationId "com.example.hp.navigationexercise" minSdkVersion 11 targetSdkVersion 22 versionCode 1 versionName "1.0" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro' } } } dependencies { compile fileTree(dir: 'libs',include: ['*.jar']) compile('com.twitter.sdk.android:twitter-core:1.3.1@aar') { transitive = true; } }

这是我的活动

@H_404_8@public class TestActivity extends ActionBarActivity { String TWITTER_KEY="mykey"; String TWITTER_SECRET="mysecret"; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_test); /* Twitter */ TwitterAuthConfig authConfig = new TwitterAuthConfig(TWITTER_KEY,TWITTER_SECRET); Fabric.with(this,new Twitter(authConfig)); setUpTwitterButton(); } TwitterLoginButton twitterButton; private void setUpTwitterButton() { twitterButton = (TwitterLoginButton) findViewById(R.id.login_button); twitterButton.setCallback(new Callback<TwitterSession>() { @Override public void success(Result<TwitterSession> result) { Log.d("login:","twitter:success"); Log.d("Data",result.data.getUserName()); } @Override public void failure(TwitterException exception) { Toast.makeText(getApplicationContext(),"twitter Login Failed",Toast.LENGTH_SHORT).show(); } }); } @Override public void onActivityResult(int requestCode,int resultCode,Intent data) { super.onActivityResult(requestCode,resultCode,data); // Pass the activity result to the login button. twitterButton.onActivityResult(requestCode,data); } }
