android debugger does not stop at breakpoints

问题

I am seeing debug statements in the console but the debugger does not stop on any breakpoints. I tried clearing all breakpoints and adding them back in. Not sure how this can happen but it is.

回答1:

Have you set the debuggable flag in the AndroidManifest? If you miss that, do so by adding android:debuggable="true" in the application tag. It should look like that in the end:

<application android:icon="@drawable/icon" android:label="@string/app_name" android:debuggable="true">

回答2:

If you use Android studio, click debug app instead of run app:

回答3:

In my case, click the "Attach debugger to Android process"

And it will shows a window said "Choose Process" Select the device you are using, and select the project that you want to debug. And it works.

Sometimes the debugger need to re-attach to the devices when you open the debugger at the first time.

According to this answer, Inside build.gradle for your app module, disable minifyEnable for your build variant and change it to false. Then, it should be:

minifyEnabled false

othewise you will see Line number not available in class xxxx when you hover over breakpoint markers and they will be looked with a cross on them

回答5:

For Android Studio:

• Check if the option Mute Breakpoints is enabled by mistake. The icon looks like this:

For Eclipse:

• Check if the option "Skip All Breakpoints" is enabled by mistake. It is the last icon on the following toolbar
  

回答6:

Did you do "Debug As --> Android Application" instead of "Run As"?

Only if you do "Debug As", eclipse will stop at breakpoints.

回答7:

Solution that worked for me:

• Simply uninstall the app from the device (manually on the device) and try debugging again(!)

回答8:

I had the same issue and resolved it by increasing the debugger timeout values. The emulator is slow as a dog on my Dev box and that is what prevented the debugger to catch and stop on breakpoints. I changed the timeout values respectively from 3000 to 10000 and 20000 to 60000 and all is fine now.
