我正在努力使應用程序在另一個應用程序(稱爲CSipSimple)中與外部服務進行通信。我可以綁定到服務:AIDL服務的java.lang.VerifyError
ServiceConnection mConnection = new ServiceConnection(){
@Override
public void onServiceConnected(ComponentName comp, IBinder svc){
ISipService mSvc = ISipService.Stub.asInterface(svc); // Exception here
...
}
...
}
Intent i = new Intent("com.csipsimple.service.SipService");
getApplicationContext().bindService(i, mConnection, BIND_IMPORTANT)
在指定的行上引發異常。我已搜索周圍,嘗試了所有的以下的,都無濟於事:
- 添加AIDL文件到項目
- 添加其他應用程序(CSipSimple)作爲必需項目的源文件夾
- 檢查了所有的條目中的訂單/導出列表
- 清洗和重建這兩個應用程序
生成以下錯誤:

看起來它無法找到一些必需的類/方法,但我已將所有AIDL文件添加到我的項目中。任何幫助將不勝感激!
看起來像'ISipService.Stub.onTransact(Parcel,Parcel,int)'傳遞'Object []'到'Parcel.writeTypedArray(Parcelable [])'。缺少方法和類通常會導致運行時失敗(「沒有這種方法」),而不是立即驗證失敗,所以第一對失敗消息可能不是致命的。 – fadden
