Der Code java ist

public void login(View v) { 
    email = edtLogin.getText().toString(); 
    pwd = edtPassword.getText().toString(); 

    postParam = new HashMap<String, String>(); 
    postParam.put("username", email); 
    postParam.put("password", pwd); 
    postParam.put("grant_type", "password"); 

    JSONObject object = new JSONObject(postParam); 
    Type type = new TypeToken<LoginResponse>() { 
    }.getType(); 
    // GeneralRequest.login(LoginActivity.this, type, object, LoginActivity.this, LoginActivity.this); 
    callApi(postParam); 
} 

XML where the method is called: 
<Button 
    android:id="@+id/login" 
    android:layout_width="@dimen/width_400" 
    android:layout_height="wrap_content" 
    android:background="@drawable/btn_background" 
    android:layout_below="@+id/password" 
    android:layout_centerHorizontal="true" 
    android:onClick="login" 
    android:text="Login" 
    android:textStyle="bold" 
    android:textAllCaps="false" 
    android:layout_marginTop="@dimen/margin_corner" 
    android:textColor="@android:color/white" 
    /> 

Gradle APP FILE-

apply plugin: 'com.android.application' 

android { 
compileSdkVersion 23 
buildToolsVersion "24.0.0 rc2" 

defaultConfig { 
    applicationId "com.mycompany.soilreport"

} 

dexOptions { 
    incremental = true; 
    preDexLibraries = false 
    javaMaxHeapSize "4g" // 2g should be also OK 
} 
}

} 

Dinge, die ich bisher versucht:

1. erneut gestartet android Studio
2. erneut gestartet geny Bewegung
3. meinen Laptop neu gestartet.
4. das Projekt Geklonte wieder
5. für die Java-Version überprüft und gradle Version
6. Uninstalled erklären die apk und wieder installiert
7. Auf die Initialisierung aller Variablen

Kann jemand bitte, warum ich ein Problem mit dieser Build-Datei?

Answer 1

public class MainActivity extends Activity { 

public void login(View v) { 
email = edtLogin.getText().toString(); 
pwd = edtPassword.getText().toString(); 

postParam = new HashMap<String, String>(); 
postParam.put("username", email); 
postParam.put("password", pwd); 
postParam.put("grant_type", "password"); 

JSONObject object = new JSONObject(postParam); 
Type type = new TypeToken<LoginResponse>() { 
}.getType(); 
// GeneralRequest.login(LoginActivity.this, type, object, LoginActivity.this, LoginActivity.this); 
callApi(postParam); 
} 

//activity oncreated method and other override methods 

} 

hier bemerken, eine Sache, die ich Ihnen gezeigt habe, dass Sie Ihre Methode OnClick in Ihrer Tätigkeit setzen sollen aber außerhalb „@Override“ Methode, weil jene Aktivität Methoden erzeugt werden.
