Android Studio Beta (0.8) has a nifty new feature where it checks that some int parameters are not arbitrary integers, but rather have some properties. For example, calling something like: setContentView(R.id.textView1); will correctly report that R.id.textView1 is not a layout id (the message is "expected resource of type layout"). There are other cases of this peppered around. Understandably, this protection is lost as soon as you add your own methods into the mix, e.g. private void mySetContentView(int resourceId) { setContentView(resourceId); } I can then call mySetContentView() with any

I've been using JSLint to make me feel bad about my JavaScript. It is great, by the way. There is one check that I don't quite understand and I'd like your views, please. From jslint.com : In languages with block scope, it is usually recommended that variables be declared at the site of first use. But because JavaScript does not have block scope, it is wiser to declare all of a function's variables at the top of the function. It is recommended that a single var statement be used per function. What is the last sentance in bold really saying? I think I should be declaring multiple variables like

Is it possible to turn off the eslint rule for the whole file? Something such as: // eslint-disable-file no-use-before-define (Analogous to eslint-disable-line.) It happens to me quite often, that in a certain file, I'm breaking a specific rule on many places which is considered OK for that file, but I don't want to disable the rule for the whole project nor do I want to disable other rules for that specific file. You can turn off/change a particular rule for a file by putting the configurations at the top of the file. /* eslint no-use-before-define: 0 */ // --> OFF or /* eslint no-use-before

I tried to add the following to the root build.gradle file: subprojects { gradle.projectsEvaluated { tasks.withType(Compile) { options.compilerArgs << "-Xlint:unchecked -Xlint:deprecation" } } } But I'm getting this: FAILURE: Build failed with an exception. * What went wrong: Execution failed for task ':Libraries:ActionBarSherlock:compileRelease'. > invalid flag: -Xlint:unchecked -Xlint:deprecation What am I doing wrong? Felipe Lima This is what worked for me: (in your project's build.gradle) allprojects { gradle.projectsEvaluated { tasks.withType(JavaCompile) { options.compilerArgs << "-Xlint

I'm contributing to open source library and got lint error "Do not treat position as fixed; only use immediately and call holder.getAdapterPosition() to look it up later" for this code: @Override public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) { mAdapter.onBindViewHolder(holder, position); if (!isFirstOnly || position > mLastPosition) { for (Animator anim : getAnimators(holder.itemView)) { anim.setDuration(mDuration).start(); anim.setInterpolator(mInterpolator); } mLastPosition = position; } else { ViewHelper.clear(holder.itemView); } } I've checked that it is

Lots of internal APIs in Android are marked @hide . What exactly does this do? Another answer says that it only hides the methods from Javadoc, but that you can use reflection to access them. That makes no sense though - if they are only hidden from Javadoc then you surely wouldn't need reflection to access them. In fact I've found that I don't. I can still call some @hide methods (maybe just static ones?) and the app compiles and runs fine as far as I can tell. I just get a lint error: Note that the above code still compiles fine. I don't care about the possibility of the API being changed so
