Cartotype和Genymotion

Question

我正在用Cartotype在一個團隊中開發一個離線路由應用程序。 我們已經成功實現了MapView，當我們在真實的Android設備上測試時，它正在工作。

但是，當我使用Genymotion Emu進行測試時，在日誌貓中使用以下錯誤消息調用該活動時會崩潰。

我周圍沒有android設備，所以我需要使用模擬器。

該庫是正確的說：

<project>\libs\cartotype.jar 
    <project>\libs\armeabi\libcartotype.so 

Answer 1

Genymotion運行在x86架構。

當執行loadLibrary方法，運行時將嘗試找到庫（的.so）的文件夾app_data/libs/x86/

內要運行這個模擬器Cartotype需要支持它的應用程序。 當一個庫支持x86，libs目錄應該看起來像：

<project>\libs\myLib.jar 
    <project>\libs\armeabi\myLib.so 
    <project>\libs\x86\myLib.so 

看來Cartotype不支持的x86。因此，隨着越來越多的設備使用x86 CPU，包括Genymotion，您應該要求Cartotype支持此架構。

或者您可以嘗試查找另一個支持x86的脫機映射庫。

Answer 2

而不是使用Genymotion，使用SDK中的標準Android模擬器。因爲它模擬ARM CPU，而不是直接嘗試運行x86代碼，所以它應該只處理僅以ARM形式提供的庫。

是的，我知道這樣會比較慢，但是在這種情況下慢一點比根本不工作要好。
