I am making an app in Android Studio, now trying to debug it through adb. When I click on the word Android and the logo on the bottom bar, logcat comes up and recognizes my device. Then I see this:
What do I need to do to my app to make it "debuggable"?
FYI was developing this app in Eclipse before and adb worked fine.
There is a Debug icon on the toolbar. It looks like a little "bug" and is located right next to the Run icon (which looks like a play button). Try launching the application with that.
Edit: The following is deprecated when using Android Studio with Gradle.
There is also a debug flag in the AndroidManifest.xml file. It is located under the application tag, and should be set to "true", as follows:
<application android:debuggable="true">
</application>
In my case near any line a red circle appeared with a cross and red line with a message: "No executable code found at line ..." like in Android studio gradle breakpoint No executable code found at line.
A problem appeared after updating of build.gradle. We included Kotlin support, so a number of methods exceeded 64K. Problem lines:
buildTypes {
debug {
minifyEnabled true
Change them to:
buildTypes {
debug {
minifyEnabled false
debuggable true
Then sync a gradle with a button "Sync Project with Gradle Files". If after restarting of your application you will get an error: "Error:The number of method references in a .dex file cannot exceed 64K. Learn how to resolve this issue at https://developer.android.com/tools/building/multidex.html", then, like in The number of method references in a .dex file cannot exceed 64k API 17 add the following lines to build.gradle:
android {
defaultConfig {
...
// Enabling multidex support.
multiDexEnabled true
}
...
}
dependencies {
implementation 'com.android.support:multidex:1.0.2'
}
UPDATE
According to https://developer.android.com/studio/build/multidex.html do the following to enable multidex support below Android 5.0. Else it won't start in these devices.
Open AndroidManifest and find tag <application>. Near android:name= is a reference to an Application class. Open this class. Extend Application class with MultiDexApplication so:
public class MyApplication extends MultiDexApplication { ... }
If no Application class set, write so:
<application
android:name="android.support.multidex.MultiDexApplication" >
...
</application>
If you enable
<application android:debuggable="true">
</application>
In the application manifest.xml make sure you disable it when generating the final signed apk since this can serve as a security loop hole for attackers. Only use it if only one of your applications does not show the logs. However before considering that option try this:
Navigate to tools in the android studio
Tools==>android==>disable adb integration and again enable it
<application android:debuggable="true">
</application>
That above code is not longer a solution. You need to enable debugging inside your build.gradle file. If you have different buildTypes make sure you set "debuggable true" in one of the build types. Here is a sample code from one of my projects.
buildTypes {
debug {
debuggable true
}
release {
debuggable false
}
}
**I have deleted other lines inside the buildTypes which are not relevant to this question from my gradle file here.
Also Make sure you select the correct build variant in your android studio while doing the debugging.
Over the years I have visited this thread many times and there was always a different response that helped me. This time I figure out that it's my USB hub that was preventing debugger to work properly. As strange as it sounds, instead of having a phone connected to my computer via a USB hub, I had to connect it directly to my mac and debugging started to work.
