在開發Android應用程式時，我們可以在AndroidManifest.xml中設定其debug屬性，比如示例1
示例1
<p style="margin-top: 0px; margin-bottom: 10px; padding-top: 0px; padding-bottom: 0px;"></p><div><span class="pln">    </span><span class="tag" style="color: rgb(0, 0, 136);"><application</span></div><div><span class="pln">        </span><span class="atn" style="color: rgb(102, 0, 102);">android:icon</span><span class="pun" style="color: rgb(102, 102, 0);">=</span><span class="atv" style="color: rgb(0, 136, 0);">"@drawable/ic_launcher"</span></div><div><span class="pln">        </span><span class="atn" style="color: rgb(102, 0, 102);">android:label</span><span class="pun" style="color: rgb(102, 102, 0);">=</span><span class="atv" style="color: rgb(0, 136, 0);">"@string/app_name"</span></div><div><span class="pln">        </span><span class="atn" style="color: rgb(102, 0, 102);">android:theme</span><span class="pun" style="color: rgb(102, 102, 0);">=</span><span class="atv" style="color: rgb(0, 136, 0);">"@style/AppTheme"</span><span class="pln"> </span></div><div><span class="pln">        </span><span class="atn" style="color: rgb(102, 0, 102);">android:debuggable</span><span class="pun" style="color: rgb(102, 102, 0);">=</span><span class="atv" style="color: rgb(0, 136, 0);">"true"</span><span class="tag" style="color: rgb(0, 0, 136);">></span></div><p style="margin-top: 0px; margin-bottom: 10px; padding-top: 0px; padding-bottom: 0px;"></p>
只有android:debuggable="true"時我們才可以在手機上除錯Android程式。
但是當我們沒在AndroidManifest.xml中設定其debug屬性時:
使用Eclipse執行這種方式打包時其debug屬性為true,使用Eclipse匯出這種方式打包時其debug屬性為法false.
在使用ant打包時，其值就取決於ant的打包引數是release還是debug.

 因此在AndroidMainifest.xml中最好不設定android:debuggable屬性置，而是由打包方式來決定其值。。
  當然對於測試人員還是應該檢查該屬性的，比如使用aapt工具：
  aapt list -v -a myfile.apk
 這個命令將會列印和apk相關的所有詳細資訊，找到“android:debuggable"，它的值分為：
  0x0: debuggable false
  0xffffffff: debugabble true
  例如，在我的測試中，這一行的資訊是：
 A: android ebuggable(0x0101000f)=(type 0x12)0x0
 這說明我的Release Build已經關閉了debuggable！
 另外，還有一種測試方法：
  使用android cts測試，http://source.android.com/compatibility/cts-intro.html
  這是一種單元測試的方法，具體用到的類是android.permission.cts.DebuggableTest。
  testNoDebuggable：如果是true，說明debuggable false;
  testNoDebuggable：如果是false，說明debuggable true。
當然，我們也可以在Android應用程式中來判斷當前應用是否處於debug狀態來做一些操作，如示例2。
