Android应用程序的debug属性

在开发Android应用程序时，我们可以在AndroidManifest.xml中设置其debug属性，比如示例1

示例1

<p style="margin-top: 0px; margin-bottom: 10px; padding-top: 0px; padding-bottom: 0px;"></p><div style="margin: 0px; padding: 0px;"><span class="pln" style="margin: 0px; padding: 0px;">    </span><span class="tag" style="margin: 0px; padding: 0px; color: rgb(0, 0, 136);"><application</span></div><div style="margin: 0px; padding: 0px;"><span class="pln" style="margin: 0px; padding: 0px;">        </span><span class="atn" style="margin: 0px; padding: 0px; color: rgb(102, 0, 102);">android:icon</span><span class="pun" style="margin: 0px; padding: 0px; color: rgb(102, 102, 0);">=</span><span class="atv" style="margin: 0px; padding: 0px; color: rgb(0, 136, 0);">"@drawable/ic_launcher"</span></div><div style="margin: 0px; padding: 0px;"><span class="pln" style="margin: 0px; padding: 0px;">        </span><span class="atn" style="margin: 0px; padding: 0px; color: rgb(102, 0, 102);">android:label</span><span class="pun" style="margin: 0px; padding: 0px; color: rgb(102, 102, 0);">=</span><span class="atv" style="margin: 0px; padding: 0px; color: rgb(0, 136, 0);">"@string/app_name"</span></div><div style="margin: 0px; padding: 0px;"><span class="pln" style="margin: 0px; padding: 0px;">        </span><span class="atn" style="margin: 0px; padding: 0px; color: rgb(102, 0, 102);">android:theme</span><span class="pun" style="margin: 0px; padding: 0px; color: rgb(102, 102, 0);">=</span><span class="atv" style="margin: 0px; padding: 0px; color: rgb(0, 136, 0);">"@style/AppTheme"</span><span class="pln" style="margin: 0px; padding: 0px;"> </span></div><div style="margin: 0px; padding: 0px;"><span class="pln" style="margin: 0px; padding: 0px;">        </span><span class="atn" style="margin: 0px; padding: 0px; color: rgb(102, 0, 102);">android:debuggable</span><span class="pun" style="margin: 0px; padding: 0px; color: rgb(102, 102, 0);">=</span><span class="atv" style="margin: 0px; padding: 0px; color: rgb(0, 136, 0);">"true"</span><span class="tag" style="margin: 0px; padding: 0px; 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"时我们才可以在手机上调试Android程序。

但是当我们没在AndroidManifest.xml中设置其debug属性时:

使用Eclipse运行这种方式打包时其debug属性为true,使用Eclipse导出这种方式打包时其debug属性为法false.

在使用ant打包时，其值就取决于ant的打包参数是release还是debug.

 因此在AndroidMainifest.xml中最好不设置android:debuggable属性置，而是由打包方式来决定其值。。
  当然对于测试人员还是应该检查该属性的，比如使用aapt工具：
  aapt list -v
-a myfile.apk
 这个命令将会打印和apk相关的所有详细信息，找到“android:debuggable"，它的值分为：
  0x0: debuggable false
  0xffffffff: debugabble true
  例如，在我的测试中，这一行的信息是：
 A: android ebuggable(0x0101000f)=(type 0x12)0x0
 这说明我的Release Build已经关闭了debuggable！
 另外，还有一种测试方法：
  使用android cts测试，http://source.android.com/compatibility/cts-intro.html
  这是一种单元测试的方法，具体用到的类是android.permission.cts.DebuggableTest。
  testNoDebuggable：如果是true，说明debuggable false;
  testNoDebuggable：如果是false，说明debuggable true。

当然，我们也可以在Android应用程序中来判断当前应用是否处于debug状态来做一些操作，如示例2。
