finished with non-zero exit value

又來了...

finished with non-zero exit value 1
這個容易解，從錯誤訊習中可以找到問題。


finished with non-zero exit value 2

從eclipse轉到android studio容易發生，這個是jar的衝突。即然用了gradle來編譯程式，就要把libs中的jar通通砍了。

finished with non-zero exit value 3
記憶體不足。用這個

android {
    // Other stuffs
    dexOptions {
        javaMaxHeapSize "4g"
    }
}
