在使用Android studio過程中，使用gradle編譯的時候總會出現一些問題，下面是幾個常見問題的解決方法。

被編譯的程式碼或資源有問題（ finished with non-zero exit value 1）：

出現這種編譯異常表現是 exit value 1，一般會給出錯誤提示，所以很容易排查。這種錯誤很常見，錯誤提示有時候是在日誌中明顯的給出來了，如下示例所示：

上面錯誤提示找不到welcome_03這個drawable資源。有時候沒有明顯的提示，如下面這種錯誤：

上面這種錯誤沒有給出很顯示的提示，但是可以知道是在執行Error:Execution failed for task ':app:transformClassesWithDexForDebug'這一步出錯了，至少縮小了錯誤的排查範圍，這個時候就需要經驗來判斷了，自己之前改過什麼，自己回想一下。有時候往上面看錯誤日誌，也會發現有很明顯的錯誤提示。

• jar包衝突（finished with non-zero exit value 2） 
  主要表現為編譯後出現finished with non-zero exit value 2錯誤，原因是jar包衝突，導致的原因可能是在dependencies中使用compile files()匯入一次jar包，然後有其它jar的引入方式使用compile’com.xxx’方式，正好又引用了這個jar包，所以導致了重複引用jar包的衝突。最常見的是support-v4包的重複引用。具體報錯如下所示：

解決方案是在gradle檔案中的android程式碼塊內增加如下內容即可解決：

<code class="hljs r has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">android {

    dexOptions {
    javaMaxHeapSize <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">"4g"</span>
    }
}</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li><li style="box-sizing: border-box; padding: 0px 5px;">8</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li><li style="box-sizing: border-box; padding: 0px 5px;">8</li></ul>

或者修改android studio的安裝目錄下的bin目錄中的studio.vmoptions檔案中的Xms和Xmx兩項，將其值改大，如下所示：
