Android allows the attribute android:debuggable to be set to true in the manifest, so that the app can be debugged. By default this attribute is disabled, i.e., it is set to false, but it may be set to true to help with debugging during development of the app. However, an app should never be released with this attribute set to true as it enables users to gain access to details of the app that should be kept secure. With the attribute set to true, users can debug the app even without access to its source code.

Note that some development environments (including Eclipse/ADT and Ant) automatically set android:debuggable to true for incremental or debugging builds but set it to false for release builds.

Risk Assessment
Releasing an app with its android:debuggable attribute set to true can leak sensitive information. In addition, the app is vulnerable to decompilation, resulting in alteration to source code.Attackers can leverage the additional information they gain from debugging output to mount attacks targeted on the framework, database, or other resources used by the application.
Rule | Severity | Likelihood | Remediation Cost | Priority | Level |
|---|---|---|---|---|---|
DRD10-J | High | Probable | Low | P18 | L1 |
...
Automatic detection of the setting of the android:debuggable attribute is straightforward. It is not feasible to automatically determine whether any data that might be revealed by debugging the app is sensitive.
