r.java-file

Android Studio 2.1, Java V8 Update 91, Gradle 2.1.0 . I know that this questions has been asked many times here, but none of the recommendation solutions works out. In a sudden after compiling ready to run on Emulator, my IDE give an error at the R.id attribute. Every Java files suddenly give the same error even I don't make any changes to the file. I tried to make a new project, see if things different but the error keep coming. In my mind it could be internal error, again. Even I just update my IDE just now. The Java file; @Override protected void onCreate(Bundle savedInstanceState) { super

I'm seeing a crash on an older device that works on multiple newer devices: android.content.res.Resources$NotFoundException: Resource ID #0x7f030035 If I recall correctly you could look at the R.java to see the culprit, however in Android Studio it doesn't seem to exist. Where is the R.java so I can correlate that ID? Thanks. In Android Studio 1.1.0 the R.java file is under Project/app/build/generated/source/r/debug/com.android.'projectname'/R.java If you don't see the above collection of folders, clean and build the project first. It takes a few minutes and you'll see Gradle running at the

I am trying to figure out what it mean to "compile resources". What I did in order to understand this issue: I have read many articles about the subject but didn't find a simple answer. The best one I have read was this: How does the mapping between android resources and resources ID work? . How I understand it: From my understanding, when we compile our project either by ANT (Eclipse) or Gradle (AS). We use a tool called aapt - Android Asset Packaging Tool which: Is used to generate unique IDs for each of our resources, such as our layouts, our styles and more and store them in a lookup table

In android 2.1 & 2.2 R.java file is auto-generated. But in 2.0 platform we have to built R.java file. anyone know how to generate R.java file from program. Use clean and build in eclipse, R.java is "Generated" every time when you build your android project. I agree with Prasham but sometime it does not works. See my comment below: - After few hours frustration of cleaning and building the project again and again, finally I have decide to remove the red marks from the my file where it was not able to resolve the R.java as it was not actually available in my code. After removing the first red

I am trying to manually implement the actions that must take place when the up button on the actionbar is pressed but for some reason nothing happens when I press it. here is my code: public class ActivityOne extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_activity_one); Toolbar toolbar = (Toolbar)findViewById(R.id.toolbar_actionbar); setSupportActionBar(toolbar); getSupportActionBar().setDisplayHomeAsUpEnabled(true); Button button = (Button)findViewById(R.id.btn1); button

I had R.java file in my android application. But I don't know, It is delete some how. To create it again I clean my project and also Rebuild my project by clicking on Build Project. I do not know what is the problem. It is not getting created again. Generally It gets created automatically whenever I build project. Some quick solutions to your problem might be, use the Ctrl + Shift + O command to "Organize Imports" and generate any missing import statements. Sometimes this would generate the incorrect import statement which would hide the R.java class that is automatically generated when you
