(#) Using `android.media.ExifInterface` !!! WARNING: Using `android.media.ExifInterface` This is a warning. Id : `ExifInterface` Summary : Using `android.media.ExifInterface` Severity : Warning Category : Correctness Platform : Android Vendor : Android Open Source Project Feedback : https://issuetracker.google.com/issues/new?component=192708 Since : 3.0.0 (October 2017) Affects : Kotlin and Java files Editing : This check runs on the fly in the IDE editor Implementation : [Source Code](https://cs.android.com/android-studio/platform/tools/base/+/mirror-goog-studio-main:lint/libs/lint-checks/src/main/java/com/android/tools/lint/checks/ExifInterfaceDetector.java) Tests : [Source Code](https://cs.android.com/android-studio/platform/tools/base/+/mirror-goog-studio-main:lint/libs/lint-tests/src/test/java/com/android/tools/lint/checks/ExifInterfaceDetectorTest.java) The `android.media.ExifInterface` implementation has some known security bugs in older versions of Android. There is a new implementation available of this library in the support library, which is preferable. (##) Example Here is an example of lint warnings produced by this check: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~text src/test/pkg/ExifUsage.java:3:Warning: Avoid using android.media.ExifInterface; use androidx.exifinterface.media.ExifInterface instead [ExifInterface] import android.media.ExifInterface; --------------------------- src/test/pkg/ExifUsage.java:13:Warning: Avoid using android.media.ExifInterface; use androidx.exifinterface.media.ExifInterface instead [ExifInterface] android.media.ExifInterface exif2 = --------------------------- src/test/pkg/ExifUsage.java:14:Warning: Avoid using android.media.ExifInterface; use androidx.exifinterface.media.ExifInterface instead [ExifInterface] new android.media.ExifInterface(path); --------------------------- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Here is the source file referenced above: `src/test/pkg/ExifUsage.java`: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~java linenumbers package test.pkg; import android.media.ExifInterface; @SuppressWarnings("unused") public class ExifUsage { // platform usage private void setExifLatLong(String path, String lat, String lon) throws Exception { ExifInterface exif = new ExifInterface(path); exif.setAttribute(ExifInterface.TAG_GPS_LATITUDE, lat); exif.setAttribute(ExifInterface.TAG_GPS_LONGITUDE, lon); exif.saveAttributes(); android.media.ExifInterface exif2 = new android.media.ExifInterface(path); } } ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ You can also visit the [source code](https://cs.android.com/android-studio/platform/tools/base/+/mirror-goog-studio-main:lint/libs/lint-tests/src/test/java/com/android/tools/lint/checks/ExifInterfaceDetectorTest.java) for the unit tests for this check to see additional scenarios. The above example was automatically extracted from the first unit test found for this lint check, `ExifInterfaceDetector.testAndroidX`. To report a problem with this extracted sample, visit https://issuetracker.google.com/issues/new?component=192708. (##) Suppressing You can suppress false positives using one of the following mechanisms: * Using a suppression annotation like this on the enclosing element: ```kt // Kotlin @Suppress("ExifInterface") fun method() { problematicStatement() } ``` or ```java // Java @SuppressWarnings("ExifInterface") void method() { problematicStatement(); } ``` * Using a suppression comment like this on the line above: ```kt //noinspection ExifInterface problematicStatement() ``` * Using a special `lint.xml` file in the source tree which turns off the check in that folder and any sub folder. A simple file might look like this: ```xml <?xml version="1.0" encoding="UTF-8"?> <lint> <issue id="ExifInterface" severity="ignore" /> </lint> ``` Instead of `ignore` you can also change the severity here, for example from `error` to `warning`. You can find additional documentation on how to filter issues by path, regular expression and so on [here](https://googlesamples.github.io/android-custom-lint-rules/usage/lintxml.md.html). * In Gradle projects, using the DSL syntax to configure lint. For example, you can use something like ```gradle lintOptions { disable 'ExifInterface' } ``` In Android projects this should be nested inside an `android { }` block. * For manual invocations of `lint`, using the `--ignore` flag: ``` $ lint --ignore ExifInterface ...` ``` * Last, but not least, using baselines, as discussed [here](https://googlesamples.github.io/android-custom-lint-rules/usage/baselines.md.html).
