Android應用程序崩潰在http post發送okhttp

Question

你好傢伙即時嘗試設置登錄屏幕，我正在使用Web服務進行登錄驗證。 Web服務正在我的本地機器上運行，並且它在登錄成功時應該使用用戶標識進行響應。目前該應用程序具有所有權限，因此它不是一個明顯的問題

我使用okhttp：3.4.1爲此。

這是觸發登錄方法

btnLogin.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     { 
      StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder() 
        .permitAll().build(); 
      StrictMode.setThreadPolicy(policy); 
      //Intent mainMenu = new Intent(LoginActivity.this, MainMenu.class); 
      //LoginActivity.this.startActivity(mainMenu); 

      LoginImpl li = new LoginImpl(); 
      int userID = li.login(txtUsername.getText().toString(), txtPassword.getText().toString()); 

      new AlertDialog.Builder(LoginActivity.this) 
        .setTitle("TEST") 
        .setMessage("USER ID = " + userID) 
        .setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() { 
         public void onClick(DialogInterface dialog, int which) { 

         } 
        }) 
        .setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() { 
         public void onClick(DialogInterface dialog, int which) { 

         } 
        }) 
        .setIcon(android.R.drawable.ic_dialog_alert) 
        .show(); 
     } 

    } 
}); 

這是被調用時，使用登錄類的按鈕：

package diplomski.thop.thopmobileclient.controller.requests; 
import java.io.IOException; 
import com.google.gson.Gson; 
import diplomski.thop.thopmobileclient.controller.implementation.Urls; 
import diplomski.thop.thopmobileclient.model.User; 
import okhttp3.OkHttpClient; 
import okhttp3.Request; 
import okhttp3.RequestBody; 
import okhttp3.Response; 

public class LoginRequest { 

    OkHttpClient client; 

    public LoginRequest() { 
     client = new OkHttpClient(); 
    } 

    public int sendLoginRequest(String username, String password) { 
     User user = new User(username, password); 
     String requestJson = new Gson().toJson(user); 
     RequestBody body = RequestBody.create(Urls.JSON, requestJson); 
     Request request = new Request.Builder().url(Urls.LOGIN_URL).post(body).build(); 
     try (Response response = client.newCall(request).execute()) { 
      String returnResponse = response.body().string(); 
      if (returnResponse.equalsIgnoreCase("Fail")) { 
       return -1; 
      } else { 
       return Integer.parseInt(returnResponse); 
      } 
     } catch (IOException e) { 
      e.printStackTrace(); 
      return -1; 
     } 
    } 

} 

這是使用URL IM：

public static final String START_URL = "http://10.0.2.2:8080/ThopWebService/rest/"; 
public static final String LOGIN_URL = START_URL + "user/login"; 

Web服務正在本地主機上運行，​​並使用模擬器即時通訊，所以我發現即時通訊應該使用t帽子ip。

每當我點擊登錄，我到try (Response response = client.newCall(request).execute())，然後我得到以下的崩潰消息。

我與Android的經驗非常有限，所以我不知道如何解決這個問題。通過搜索錯誤找不到解決方案。

編輯：添加我的build.gradle

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 24 
    buildToolsVersion "24.0.2" 

    defaultConfig { 
     applicationId "diplomski.thop.thopmobileclient" 
     minSdkVersion 19 
     targetSdkVersion 24 
     versionCode 1 
     versionName "1.0" 
    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 

} 

dependencies { 
    compile fileTree(include: ['*.jar'], dir: 'libs') 
    testCompile 'junit:junit:4.12' 
    compile 'com.android.support:appcompat-v7:24.2.0' 
    compile 'com.android.volley:volley:1.0.0' 
    compile group: 'com.google.code.gson', name: 'gson', version: '2.6.2' 
    compile 'com.squareup.okhttp3:okhttp:3.4.1' 
} 

Answer 1

你跟傑克編譯？我可以看到Square庫（okhttp，picasso）在使用Jack時出現VerifyError（https://code.google.com/p/android/issues/detail?id=82691）。

檢查你的gradle模塊級構建文件，並檢查是否啓用了Jack。這樣的事情：

jackOptions { 
    enabled true 
    }
