* Refactor lint folder structure.Xavier Ducrohet2012-12-061-2/+2
| | | | | | | | | | Move folders around to match default gradle/maven folder structure. The custom structure confused some IDEs when importing the project as a Gradle project. Change-Id: I5c059cc6fdf0ac2444b03d435f83f853363cfa32
* Warn about non-recent targetSdkVersionsTor Norbye2012-08-231-0/+1
| | | | | | | | | | | | | | This changeset changes the default targetSdkVersion written into new projects from being hardcoded to "15" to being the same level as the build target's API level. It also adds a new lint check which looks at the targetSdkVersion and complains if it's not the same as the highest known version (currently 16). The issue explanation points to the javadocs for the android.os.Build.VERSION_CODES class for details on how to upgrade the app. Change-Id: I00c2bd7cd8fa239b9fd1de9b2d35ff9faf87d25f
* Refactor common.jarXavier Ducrohet2012-08-071-3/+4
| | | | | | | | | | | | | | | Move resources and com.android.util.Pair into layoutlib_api where they belong since layoutlib depends on them and we need to control the API. Made a copy of Pair to stay in common.jar but moved it to com.android.utils.Pair (the one in com.android.util.Pair is marked as deprecated to prevent usage where applicable). Also moved XmlUtil and PositionXmlParser to com.android.utils to match Pair. Change-Id: I21d7057d3f2ce604f86a3bb1fa3c130948c93b89
* Dynamically link Guava and ASM in lint jarsTor Norbye2012-03-191-2/+1
| | | | | | | | | | The Makefiles for the lint, lint_api and lint_check libraries were *statically* linking in the Guava and ASM libraries. This made them much larger than necessary (~1.6M instead of ~100K), and for no good reason since the classes were already on the classpath, and of course this duplicates them repeatedly.

* Lint Java source supportTor Norbye2012-01-091-1/+2
| | | | | | | | | | | | | | | | | This changeset adds Java AST support to Lint. There are new interfaces for Java parser and specialized Java detectors. Java detectors can either visit a full parse tree, or they can register interest in specific methods, or Android resource references, or specific AST node types -- or a combination of these. They will then be invoked during an AST visit with the relevant info. This changeset also rewrites the existing detectors that were using String-based pattern checking on Java files to using real AST traversal instead (and it removes the custom Eclipse-specific unused resource detector since the plain one now does the same AST-based analysis that the Eclipse one did.)

* Add the Guava library to the toolsTor Norbye2011-12-051-1/+2
| | | | | | | | | | | | This changeset adds the Guava library to ADT and lint. (It is also a prerequisite for the Lombok AST library which is added by a later CL.) This changeset also uses the library in a few simple ways: It replaces some custom I/O and collections code with calls into the equivalent Guava methods, and it also adds the @Beta annotation on the various "API" classes which are not yet stable.

* Static analyzerTor Norbye2011-10-201-0/+31
This changeset adds a static analyzer, "lint", which looks for various potential bugs in Android projects. It has 3 parts: (1) A library which performs the actual static checks. This library is standalone: it does not depend on Eclipse. (Technically the library has two halves: an API half, for use by third party developers to write additional detectors, and an actual implementation of a bunch of built-in checks.) (2) A command line driver, "lint", which runs the static checks and emits any warnings to standard out. This can be thought of as a replacement for the layoutopt tool. (3) Eclipse integration. Lint errors are added to the Problems view as well as shown as editor annotations. There's an options panel for controlling which detectors are enabled. There's also a quickfix for disabling errors directly within the editor and a marker resolution for disabling them via the Problems view. The static checks are run on an XML file right after it has been saved. (This is optional via a toggle on the same preference page as the detector list.) The static checks are also run when you export an APK, and if any fatal errors are found the export is abandoned. (This is also optional via an option). Finally you can run a full lint through the Android Tools menu, and there's also an action to clear all the lint markers there. There's also a new indicator on the layout editor which shows whether there are lint errors on the associated file, and when clicked brings up a dialog listing the specific errors. This changeset also includes a number of checks: * An accessibility detector which warns about images missing contentDescriptions * A drawable selector detector which warns about state lists where not all states are reachable (e.g. it is not the case that only the last item in the list omits a state qualifier) * A detector finding duplicate ids, not just in the current layout but across included layouts (transitively) as well * All the layoutopt ones ported to Java + DOM * Unit tests for the above. The focus here is on getting the infrastructure in place, and it currently focuses on XML resource files and analyzing them efficiently. See the comment in XmlVisitor for details on that.
