IntelliJ Idea not generate id in R.java
android, compilation, intellij-idea, java
Solution
What you're observing is probably the by-design behaviour in Idea 12:
http://youtrack.jetbrains.com/issue/IDEA-99045
"It is behaviour of IDEA 12, it doesn't generate full R.java in gen folder, it generates it in the IDEA's system dir during compilation."
In your case, look into `~/.IntelliJIdea12\system\compiler\YOUR_PROJECT_NAME.RANDOM_STRING\.generated\aapt\YOUR_PROJECT_NAME.RANDOM_STRING\production\package\R.java`
This file should be up to date and it should contain all the IDs you expect.
It should also be hooked up to Idea's functionalities of autocompletion, usage search etc by some sort of internal Idea magic.
The empty R.java is normal (although misleading, and Jetbrains intends to change this behaviour).
Problem
I recently switched to IntelliJ Idea 12. Now created a project on android and immediately ran into a problem: not generated id in R.java Rebuild project does not help. Maybe in IntelliJ Idea have any subtlety is not known to me? error: ``` 12-01 16:08:15.067: ERROR/AndroidRuntime(7108): FATAL EXCEPTION: main android.content.res.Resources$NotFoundException: String resource ID #0x1 at android.content.res.Resources.getText(Resources.java:266) at android.widget.TextView.setText(TextView.java:3624) at com.example.poem_new.MyActivity.invalidateCounters(MyActivity.java:41) at com.example.poem_new.MyActivity.access$000(MyActivity.java:11) at com.example.poem_new.MyActivity$1.onTextChanged(MyActivity.java:29) at android.widget.TextView.sendOnTextChanged(TextView.java:8027) at android.widget.TextView.handleTextChanged(TextView.java:8074) at android.widget.TextView$ChangeWatcher.onTextChanged(TextView.java:8454) at android.text.SpannableStringBuilder.sendTextChange(SpannableStringBuilder.java:892) at android.text.SpannableStringBuilder.change(SpannableStringBuilder.java:352) at android.text.SpannableStringBuilder.change(SpannableStringBuilder.java:266) at android.text.SpannableStringBuilder.replace(SpannableStringBuilder.java:443) at android.text.SpannableStringBuilder.replace(SpannableStringBuilder.java:420) at android.text.SpannableStringBuilder.replace(SpannableStringBuilder.java:29) at android.view.inputmethod.BaseInputConnection.replaceText(BaseInputConnection.java:669) at android.view.inputmethod.BaseInputConnection.commitText(BaseInputConnection.java:188) at com.android.internal.widget.EditableInputConnection.commitText(EditableInputConnection.java:149) at com.android.internal.view.IInputConnectionWrapper.executeMessage(IInputConnectionWrapper.java:315) at com.android.internal.view.IInputConnectionWrapper$MyHandler.handleMessage(IInputConnectionWrapper.java:85) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:154) at android.app.ActivityThread.main(ActivityThread.java:4945) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:511) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:784) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:551) at dalvik.system.NativeStart.main(Native Method) ``` R.java file is empty: ``` /* This stub is for using by IDE only.
