在Android中集成PayPal时出错

Question

我是Android新手，我尝试在Android中集成PayPal。我按照这个官方教程

https://github.com/paypal/PayPal-Android-SDK/blob/master/docs/single_payment.md

我有以下错误

uses-sdk:minSdkVersion 15 cannot be smaller than version 16 declared in library [com.paypal.sdk:paypal-android-sdk:2.14.3] /home/developer/Desktop/Jac - Android/jac/build/intermediates/exploded-aar/com.paypal.sdk/paypal-android-sdk/2.14.3/AndroidManifest.xml 
    Suggestion: use tools:overrideLibrary="com.paypal.android.sdk.payments" to force usage 

我写在menifest文件此代码，这个错误删除：

xmlns:tools="http://schemas.android.com/tools"> 
    <uses-sdk tools:overrideLibrary="com.paypal.android.sdk.payments"/> 

但它产生几更多错误：

FATAL EXCEPTION: OkHttp Dispatcher 
Process: com.knysys.jac.jaclassified, PID: 1982 
java.lang.NoSuchMethodError: No virtual method log(Ljava/lang/String;)V in class Lokhttp3/internal/Platform; or its super classes (declaration of 'okhttp3.internal.Platform'

at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:587) 
at java.lang.Thread.run(Thread.java:818) 

我有我的gradle这个这些依赖仍然我得到这些问题

compile 'com.squareup.retrofit2:retrofit:2.0.0-beta3' 
    compile 'com.squareup.retrofit2:converter-gson:2.0.0-beta3' 
    compile 'com.squareup.okhttp3:logging-interceptor:3.0.0-RC1' 

如果我错了。为什么它会产生这样的错误。任何帮助或任何其他解决方案来实现这一点。谢谢。

让您清单的变化： -

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
     package="com.javatpoint.hello" 
     android:versionCode="1" 
     android:versionName="1.0" > 

     <uses-sdk 
      android:minSdkVersion="" //change minSDK to 16 or more 
      android:targetSdkVersion="" /> //change targetSdk to 19 or more 

     <application 
      android:icon="@drawable/ic_launcher" 
      android:label="@string/app_name" 
      android:theme="@style/AppTheme" > 
      <activity 
       android:name=".MainActivity" 
       android:label="@string/title_activity_main" > 
       <intent-filter> 
        <action android:name="android.intent.action.MAIN" /> 

        <category android:name="android.intent.category.LAUNCHER" /> 
       </intent-filter> 
      </activity> 
     </application> 

    </manifest>
