logcat alike overlay to display log messages in your app as independent overlay.
Typically in android you would log some app internals for debugging puropose by using
Log.d(). However, sometimes you may need to display that logging messages right on the screen to make them visible for non developers that have to verify certain app internals, like tracking.
This tiny library adds an overlay as independent
Window on top of your android application. You can close this
DebugOverlay-Window by clicking on the close button. The window will then automatically pop up again when the next message to log is detected.
How to use it
DebugOverlay.with(context).log("My logging message");
Obviously you wont deliver this
DebugOverlay with you production code in the play store .apk file. Hence this library provides two maven artifacts to include.
debugCompile('com.hannesdorfmann:debugoverlay:0.4.0') // Starts the service and displays the overlay releaseCompile('com.hannesdorfmann:debugoverlay-noop:0.4.0') // Does nothing
The idea is to use gradle build types to add the
DebugOverlay only to debug builds.
debugoverlay is the real implementation and displays the window while
debugoverlay-noop is a stub and simply does nothing!
Please note that
com.hannesdorfmann:debugoverlay:0.4.0 will add
android.permission.SYSTEM_ALERT_WINDOW to your apk. Hence you should avoid to use that dependency for your release
The api is very simple. You can simply log string messages. You can open new issues here on github to make a new feature request. If it is not too complicated and will not add a lot of new methods to the public API (dex count 65k limit) then it's very likely that we can add this feature to this library.
