Where will the AAPT2 logs be saved? While migrating to gradle-plugin-3.0.0, I am getting this exception.

Just add this line as per your compileSdkVersion

buildToolsVersion "27.0.3"

I was also getting same error because of using & character directly in layout xml. So, please be careful about using html entities in your project.

AAPT2 Error solution.

If your Android studio has been updated.

Maybe, you would face an error in the studio like "AAPT 2 error: check the log for details"

This error will occur when you have done something wrong in your .xml file such as incorrect value, content not found, etc.

But, At that time you will not have the error specification there. Because the new version of Android Studio does not give you a specific error. It gives like AAPT2 error.

If you want to know where the actual error is then

Follow step.

1. Look at the panel which is at the right of your Android studio Check out the "Gradle" tab and click on it.
2. You will see the "app" option. Click on it.
3. In the app options you will see [Tasks -> build] click on it.
4. Then you will get options list and see "assembleDebug" double click on it.
5. Keep the patience and See build tab at the bottom panel of Android studios, you will get an exact error there what you made a mistake in which file and which position.

someone might get some help from my case I just put a hard coded color hex value without # like this by mistake android:textColor="FFA500" almost made me mad to findout. #FFA500 this solved my issue

Ensure if no image in drawable folder is corrupted.

Check the latest edited XML file. It is the main Villian I had once such error, I then checked the last xml file, ther was a line like android:layout_marginTop="." I changed it to android:layout_marginTop="16dp". That fixed the bug!

Seeing your logs :

at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) ... 1 more Caused by: com.android.tools.aapt2.Aapt2Exception: AAPT2 error: check logs for details at com.android.builder.png.AaptProcess$NotifierProcessOutput.handleOutput(AaptProcess.java:454) at com.android.builder.png.AaptProcess$NotifierProcessOutput.err(AaptProcess.java:411) at com.android.builder.png.AaptProcess$ProcessOutputFacade.err(AaptProcess.java:332) at com.android.utils.GrabProcessOutput$1.run(GrabProcessOutput.java:104)

I feel some PNG files are corrupted and were not parsed. Sometimes the images have an extension but are not real PNG.

You can check if the images in your project are real PNGs with the below command :

find . -type f -name "*.png" | xargs -L 1 -I{} file  -I {} | grep -v 'image/png; charset=binary$'

After getting the list use this site to convert them to PNG. Then check your build again.

some symbols should be transferred like '%'

<string name="test" formatted="false">95%</string>

This resolved the issue for me... Build|Clean project Refactor|Remove unused resources I am still a beginner at this so I cannot explain why this might have worked. It was an arbitrary choice on my part; it was simple, did not require detailed changes and I just thought it might help :)

possible issue related to this can be with your XML files. I have faced this when I deleted my unnecery xml files.

For remedy from this error in gradle.properties of the module, add this below line:

android.enableAapt2=false

after adding this line, restart the gradle.

and do once clean, rebuild your project.

If you are getting this error only when you are generating signed Apk . Then the problem might be in one or more of the imported media file format. I have used an image directly from net to studio and was not able to generate sign apk, then found the error .

from Gradle >assembleRelease then got the error in console. see the error log in console image.

If you are seeking a way to get to the heart of the issue. Android studio contains a feature within the edit configurations panel that simplifies this possible. By clicking on the "app" tag (It is typically to the left of the top run button)

You will open the option to edit configurations. From there create an instance of the gradle option to yourself.

The core features are actually the gradle project as well as the task. Connect the task to your debug initiative.

When you run your app through this setting, Android will spit out detailed errors(That we all wish would appear more often) and these errros will point directly a what needs to be resolved.

style="?android:attr/android:progressBarStyleSmall"

to

style="?android:attr/progressBarStyleSmall"

I made a stupid mistake. In my case, I made the project path too deep. Like this: C:\Users\Administrator\Desktop\Intsig_Android_BCRSDK_AndAS_V1.11.18_20180719\Intsig_Android_BCRScanSDK_AndAS_V1.10.1.20180711\project\as\AS_BcrScanCallerSvn2

Please migrate the project to the correct workspace. Hope this helps someone in future.

I fixed the ERROR with three steps
1. I checked for the problem SOURCE
2. Provided the correct string/text, because it was the CAUSE
3. I cleaned the project, you ll see it under BUILD.

Just in case above solution did not work. In my case , Bitdefender Antivirus was Preventing AAPT2 from making change on certain file.

You have a problem with a png file maybe, look here :

1 more Caused by: com.android.tools.aapt2.Aapt2Exception: AAPT2 error: check logs for details at com.android.builder.png.AaptProcess$NotifierProcessOutput.handleOutput(AaptProcess.java:454)

It can be corrupted image or jpeg image with png extension

I had this error and no meaningful message to tell me what was wrong. I finally removed this line from gradle.properties and got a meaningful error message.

android.enableAapt2=false

In my case somebody on the team had changed a .jpg extension to a .png and the file header didn't match the extension. Fun.

I tried every possible solution to fix this frustrating error and only below worked for me. In your build.gradle add this:

android {
    aaptOptions.cruncherEnabled = false
    aaptOptions.useNewCruncher = false  }

For me, I got this error while working on some Udacity projects. I fixed it by adding the following code to the top-level build.gradle file.

allprojects {
    String osName = System.getProperty("os.name").toLowerCase()
    if (osName.contains("windows")) {
        buildDir = "C:/tmp/${rootProject.name}/${project.name}"
    }
    repositories {
        jcenter()
        google()
    }
}

I faced similar problem. Akilesh awasthi's answer helped me fix it. My problem was a little different. I was using places_ic_search icon from com.google.android.gms:play-services-location The latest version com.google.android.gms:play-services-location:15.0.0 does not provide the icon places_ic_search. Because of this there was a problem in the layout.xml files.That led to build failure AAPT2 error: check logs for details as the message. Android studio should be showing cannot find drawable places_ic_search as the message instead.

I ended up using a lower version of com.google.android.gms:play-services-location temporarily. Hope this helps someone in future.

The error might be cause by non-ASCII symbols in gradle path. E.g. cyrillic symbols of the user folder. So, the problem is solved just by switching to another directory with ASCII-only path.
