How to remove lint errors in android studio - android

when i was trying to execute my android studio wear application it shows lint error.
Here is my log :
Error:Execution failed for task ':wear:lint'.
> Lint found errors in the project; aborting build.
Fix the issues identified by lint, or add the following to your build script to proceed with errors:
...
android {
lintOptions {
abortOnError false
}
}
...

Add this to your build.gradle file
android {
lintOptions {
abortOnError false
}
}

Add this to your module level build.gradle file
> lintOptions {
> abortOnError false
> }
This will stop aborting of gradle if any lint error found, even though this is not recommended.
Alternatively you can just go to yourproject>app>build>results>lint_error.htmland then see errors and solve them or, you can also go for,
Analyze>Inspect Code and solve errors beforehand.
Hope this will solve your query.

Lint found fatal errors

While generating release in android studio Build--> Generating signed Bundle/APK(s), I got below message
"Lint found fatal errors while assembling a release target", because of this I am unable to generate the release build
Try this:
lintOptions {
checkReleaseBuilds false
}
to app level build.grade file within the android{ } section.
In your Android Studio, switch to the Project pane. Go app --> build
--> reports --> lint-results-prodRelease-fatal.xml
Here android studio will open the file explaining the error, message, and the place and line number where it has occurred.
Now in 2022, the path to lint output might be changed. please check in For me I found the error mentioned in this path
app\build\intermediates\lint_vital_intermediate_text_report\release\lint-results-release.txt
a work around but will not solve the real problem and you might face troubles in production is to change below true to false. but I don't recommend it.
android {
lintOptions {
checkReleaseBuilds true
abortOnError true
}

How to configure lint by gradle options from command line?

Is there any way to set abortOnError false for lint by command line options of gradle/gradlew, without gradle config changing?
There may be a more direct way to do this, but I recently solved this problem by setting abortOnError based on a project property that can be overwritten from the command line.
Something like this:
lintOptions {
abortOnError project.hasProperty("abortOnLintError") ? project.getProperty("abortOnLintError").toBoolean() : false
}
By default, abortOnError is set to false, but if you want to overwrite it to true from the command line, you can:
./gradlew lintDebug -PabortOnLintError=true

Add lint to CI and mark a build fail when lint produces errors for Android Studio projects

I need the Gradle build to be marked as a failure and it should be stopped automatically if running lint gives me an error. I made the changes in code as required but it did not result in any change.
Code:
lintOptions {
// set to true to turn off analysis progress reporting by lint
quiet true
// if true, stop the gradle build if errors are found
abortOnError true
// if true, only report errors
ignoreWarnings false
}
Also apart from it, I need to add lint to CI. The CI software I use is Jenkins. SO I need to configure their android linting plugin of Jenkins such that the build is stopped and marked Failure if Lint gives an error.
I am very new to lint and CI, so please provide a detailed answer.
You don't need the Lint Jenkins plugin. Just put something this in your JenkinsFile.
try {
sh './gradlew lint'
} finally {
step([$class: 'ArtifactArchiver', artifacts: 'app/build/reports/staticAnalysis/lint/', fingerprint: true])
}
ArtifactArchiver is just to collect artifacts after lint check.

Gradle build: Execution failed for task ':app:lint'

I'm using Android Studio 2.0 and I was trying to running my program when something strange happened. I ran the build command of the gradle and I got this error:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:lint'.
> Lint found errors in the project; aborting build.
Fix the issues identified by lint, or add the following to your build script to proceed with errors:
...
android {
lintOptions {
abortOnError false
}
}
...
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
BUILD FAILED
Total time: 4.197 secs
Lint found errors in the project; aborting build.
Fix the issues identified by lint, or add the following to your build script to proceed with errors:
...
android {

}
}
...
10:41:28: External task execution finished 'build'.
And so... What the hell is that? I'm supposed to do to solve this problem adding the code to the gradle.build, but the question is: why I got this error message?
Please save me guys!
Add this in your app/build.gradle file
android {
//...
lintOptions {
abortOnError false
}
}
Switch to project view
Then, project/app/build/reports/lint-results
Now, you will find the lint-result files in two formats - 1) xml and 2) html.
You can view these files as is. However, I find viewing the lint results in a browser to be easy on the eyes. Just right-click on the html file and choose view in browser.
It opens up like the image below in my Chrome browser.
You have some lint issues while you are bulding the app module.
You can find all issues found in the report generated in Project\module\build\outputs.
Here you will find the html file and the xml file with the lint report.
Using this script in the app\build.gradle
android {
lintOptions {
abortOnError false
}
}
you can disable the block but it is not the best practice.
You should analyze the lint report to solve each point.
I think it's better to find the errors rather than ignoring them.
try this:
In Gradle Console find "Wrote HTML report to file", open the indicated HTML file and you will find a lint report
Go to your errors and fix them
Your build.gradle(Module: app) should include
android {
lintOptions {
abortOnError false
}
}
If the abortOnError false does not work, the Flutter version 2.5.1 recommend using the following arguments in the lintOptions:
android{
...
lintOptions {
checkReleaseBuilds false
}
}
Run gradle build -i instead of just gradle build. There will be lots more output than usual. Some of it will look like this:
> Task :project-name:lint FAILED
Putting task artifact state for task ':project-name:lint' into context took 0.0 secs.
Up-to-date check for task ':project-name:lint' took 0.0 secs. It is not up-to-date because:
Task has not declared any outputs.
Ran lint on variant release: 333 issues found
Ran lint on variant debug: 333 issues found
Wrote HTML report to file:///some/path/lint-results.html
Wrote XML report to file:///some/pahth/lint-results.xml
:project-name:lint (Thread[Task worker for ':',5,main]) completed. Took 1.756 secs.
Check out /some/path/lint-results.html to see why lint failed. Once those errors are fixed, your build will complete smoothly.
I got the error Execution failed for task ':app:lintVital[myBuildVariant]' and a nullpointer error. It happened after switching branches and the thing that helped for me was to do a Build -> Clean Project
Only add this code in build gradle:
android {
lintOptions {
abortOnError false
}
}
That should be enough.
If you face this issue do not add a linter disabler to your gradle,
This is an access error issue,I faced that on react-native after using sudo command for a few command,
Just reset your code access and then release again
For example the mac
sudo chmod -R 777 <project-root-folder-name>
If it remains use
preBuild.doFirst {
ant.replaceregexp(
match:'Bad gradle',
replace:'Correct one',
flags:'g',
byline:true
) {
fileset(
dir: 'Where to search',
includes: '*.java'
)
}
}
So you can fix error before release if exists in that library
The new lint way is like so
android {
lint {
isAbortOnError = false
}
}

How to sign APK on Android Studio even with non-translated strings?

Background
I've recently migrated my app to Android-Studio. I had some issues doing so, but I got over them eventually.
The problem
For some reason, on Android Studio, when I try to sign an APK, I get a lot of errors that look like this:
Error:(16) Error: "..." is not translated in "de" (German), "el" (Greek), "iw" (Hebrew) [MissingTranslation]
(where "..." is a string)
At the bottom, after a lot of errors of this kind, I see this:
Error:Execution failed for task ':app:lintVitalRelease'.
> Lint found fatal errors while assembling a release target.
To proceed, either fix the issues identified by lint, or modify your build script as follows:
...
android {
lintOptions {
checkReleaseBuilds false
// Or, if you prefer, you can continue to check for errors in release builds,
// but continue the build even when errors are found:
abortOnError false
}
}
...
The question
I'm not sure what's wrong and how I can fix it. On Eclipse I did it very easily. Missing translations shouldn't stop me from signing an APK...
To me it seems as if Lint is preventing the exporting of the APK, and that the reason is that I didn't translate all of the strings. Is that true?
Can anyone please help me? How can I fix this, so that Lint will show me just warnings instead? or a confirmation dialog if I'm sure I want to do it?
The cleanest way to solve the problem is to disable Lint checks of missing translations for release builds only.
To do so add "disable 'MissingTranslation'" to your build.gradle file as shown below:
android {
buildTypes {
release {
lintOptions {
disable 'MissingTranslation'
}
}
}
}
To me it seems as if Lint is preventing the exporting of the APK, and
that the reason is that I didn't translate all of the strings. Is that
true?
Yes. Default option is lintOptions.abortOnError = true
Can anyone please help me?
You should open the build.gradle file located at the main project module, or the generic folder if you do not have a module. Then add the suggested lines:
android {
lintOptions {
checkReleaseBuilds false
// Or, if you prefer, you can continue to check for errors in release builds,
// but continue the build even when errors are found:
abortOnError false
}
}
Some Lint warnings are by default turned to studio as errors, I don't actually know why, but in terms of translations I guess that is a way to "stop" you publishing an app that the translation is incomplete due to a last minute additions of some texts.
With the lintOptions checkReleaseBuilds abortOnError you set the checking of Lint not to run for release versions and also not stopping if an "error" is found. Below I explain where the Lint errors settings can be found, so if you want to go further you can go one step forward and read them one by one. Some of them provide helpful instructions for code optimizations.
How can I fix this, so that Lint will show me just warnings instead?
or a confirmation dialog if I'm sure I want to do it?
There is also an option at the Android Studio settings to change any Lint error to Lint warning, but I never test that. I usually turn to the gradle solution.
The option is located at Settings > Inspections > Android Lint. For easy find open Settings and at the search (located at the top) type Lint translation there you can change the translation options appear at the left from errors to warnings.
An other option if your error strings never going to be translated is to add at your XML string files tools:ignore="MissingTranslation" either at the root item or at each non-translatable string.
Simple way to solve this Error
Just add following Code To do add "disable 'MissingTranslation'" to your build.gradle file as shown below:
...
android {
lintOptions {
checkReleaseBuilds false
// Or, if you prefer, you can continue to check for errors in release builds,
// but continue the build even when errors are found:
abortOnError false
}
}
...
OR You can also Add this:
android {
buildTypes {
release {
lintOptions {
disable 'MissingTranslation'
}
}
}
}
You could try to open "Translations Editor" and set the string "..." as "Unstranlatable".
You also must remove all translations of this string.
FWIW: If you don't plan on supporting other languages, then you don't need to disable the lint checks at all. Sometimes your project setup (or a library you're importing) may have accidentally - or intentionally - included a config to support additional languages by declaring a values- folder for that language like this for instance:
<your project source folder>/main/res/values-ar
This was the case for me so I simply removed the folder. But if you have no control over the offending library then one choice is to disable lint abortOnError as indicated in the accepted answer, or find a way to exclude 'library-imported' folders somehow. For the latter option you can start here
there is many solution but i tried
<string name="hello" translatable="false">hello</string>
It's the ignore attribute of the tools namespace in your strings file, as follows:
<?xml version="1.0" encoding="utf-8"?>
<resources
xmlns:tools="http://schemas.android.com/tools"
tools:ignore="MissingTranslation" >
<!-- your strings here; no need now for the translatable attribute -->
</resources>
and from the Gradle
release {
lintOptions {
disable 'MissingTranslation'
}
}
and
android {
lintOptions {
disable 'MissingTranslation'
}
}
Working
buildTypes {
release {
lintOptions {
checkReleaseBuilds false
abortOnError false
}
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
