I am getting this error
Description Resource Path Location Type
Unknown error: Unable to build: the file dx.jar was not loaded from the SDK folder! Sample1 Unknown Android Packaging Problem
before some time it was working fine for me and I think due to some virus or something my setup got effected please help me on this???
This SO answer provides more details if removing build automatically / rebuilding doesn't work.
It worked for me.
I removed build automatically and then build whole workspace some how it worked for me :)
from Android ADT error, dx.jar was not loaded from the SDK folder:
"add this in the project.properties of your project: sdk.buildtools=25.0.2"
File-> Switch Workspace-> (new workspace) it will definitely work :)
Open Android SDK Manager.(Windows → Android SDK manager)
Go to Tools → Options.
Click on Clear Cache → Close.
Go to Packages → Reload.
Packages will be visible now under the latest downloads in SDK manager.
I tried most of the things but nothing worked for me. After spending some time i got the solution
Open {Android SDK dir}\build-tools and also open project.properties in our project
Check for sdk.buildtools=29.0.0 (If you don't have this, just add it manually)
Change 29.0.0 entry based on {Android SDK dir}\build-tools folder and start the build
Ex:
- {Android SDK dir}\build-tools i have 28.0.3. Then I've changed sdk.buildtools=28.0.3 gave the build. Not worked
- {Android SDK dir}\build-tools i have 25.0.3. Then I've changed sdk.buildtools=25.0.3 gave the build. Not worked
- {Android SDK dir}\build-tools i have 24.0.3. Then I've changed sdk.buildtools=24.0.3 gave the build. Success
After trying all these,yet haven't solve my problem then i change the SDK LOCATION: Do change the windows -> preferences-> Android-> change the SDK LOCATION FROM.It work for me
The only solution worked for me was removing the impacted versions from build tools folder.
