Sorry for Its the duplicate article, so its problem about my code completion when typing code or single words but the code suggestion not appearing and when i complete all then it just came out, or have just press Window+Space then it appearing which without that its still hidden. I look up for a lot of question about this error but none of there are worked.I also get in the Code Completion and trying to see but its still being like that.Anyway thank you so much for helping me this problem, i very admire and respect for that too
This issue with code completion can be caused by various reasons, such as a malfunctioning IDE, incorrect settings, or a damaged installation. Here are some steps you can try to resolve the issue:
Restart Android Studio: Sometimes, simply restarting the IDE can
resolve the issue.
Check the settings: Make sure that the code completion is enabled in
your IDE settings. You can do this by going to File > Settings >
Editor > General > Code Completion, and then checking if the
Auto pop-up code completion option is selected.
Invalidate caches and restart: Sometimes, the issue can be caused by
corrupted caches. You can try invalidating the caches by going to
File > Invalidate Caches / Restart.
Reinstall Android Studio: If the above steps do not resolve the
issue, you may need to reinstall Android Studio. Before you do this,
make sure to back up your important projects and settings.
I hope one of these steps resolves the issue for you.

I'm facing an issue with my Android Studio. If you look at the attachment below everything is unrecognized. Everything is in red. Autocomplete for coding is not working however, my code is 100% correct and the application works great on the mobile device.
It is so annoying... I have reinstalled Android Studio several times (fresh install) and still not working.
I don't know how to fix it. If anyone faced this issue before please let me know how you fixed it. Help a brother out am about to lose it.
Try these two options once, This might work for you
You can resolved it by clicking File > Invalidate Caches /
Restart... > Invalidate and Restart. When Android Studio restarted
and indexed all code again.
You can also try resolving it by going to
File > Sync with File System and then closing the project and
importing it again
You may need to resync with the gradle again but hopefully it works for you
Are you sure that your SDK and JDK locations are set properly?
Have a look at File -> Project Structure -> SDK Location -> Android SDK Location / JDK Location
Whenever I make a code change in the Android Studio (version 3.0.1) I need to clean before I build in order for that change to take effect. Making a change and hitting the green arrow build/run button looks like it builds but the new changes are not incorporated unless the project is cleaned beforehand. For example, if I add some logging then build/run, the new logs don't appear until I clean then build/run again. This seems to be the case for almost all changes. Sometimes it works, most of the time it doesn't.
The compiler should detect changes to the code and rebuild those files every single time. It feels like they prioritized build speed over correctness. Has anyone else solved this problem? If not then is there some setting that forces a clean before every build/run?
I had the same issue after updating Android Studio to version 3.1. It seems that the Before launch action of the default run configuration has been changed to Instant App Provision. Check it out and change to Gradle-aware Make here:
I experienced that when I left my Android Studio opened for a long time. The solutions I found were:
Hit the "Sync Project with Gradle files" button.
Restart Android Studio.
I hope this helps you.
This suddenly started:
Code changes were not being reflected on the app / were not taking effect.
My "Run / Debug configurations" settings were as said by #4emodan.
Still, i was facing the problem.
"File -> Invalidate Caches / Restart ..."<br>
made it.
This could have been the result of my machine intermittently rebooting (because of hardware issues).
I found that I had to force the apk to install on every build - or risk that some of my changes will not be present. It seems that Google has broken something with the instant run in AS 4.1.2 -- to fix it uncheck "Skip installation if APK has not changed" in the "Run app" dialog.
I am using android Studio for about 2 months, this never had happened to me. For me I did a clear and rebuild project.
My run tool of Tool windows in view is grayed out and I have no idea as to what to do to be able to use it
The Run Command is disabled when the Gradle is not built correctly.
Try Invalidating the cache.
Go to File > Invalidate Caches/Restart > Invalidate and Restart
Also, please attach the screenshot for Event Log, if above steps doesn't work for you.
The Run tool window displays output generated by your application. If you are running multiple applications, each one is displayed in a tab named after the run/debug configuration applied.
It highlight when any application in your IDE is in running state.
Got the answer. Very noob of me to ask. I should have tried a little harder. opened the gradle and pressed ctrl+shift. it worked
This morning I have been experiencing an issue with Android Studio, whenever I open it I am getting the following error.
I have tried removing Android Studio and getting a clean install. Removing all the preference folders. Removing and re-downloading my project's repository. Creating a new project. All of these still end with this error showing up. No mater how high I increase the memory it is still getting this issue.
I have checked the Activity Monitor and it is actually only using 524mb of memory. Does anyone have any suggestions?
The next thing I'm going to try is using an older version of Android studios. Apart from that I'm not sure what else to do beside a clean install of the OS and hope for the best.
UPDATE:
Couldn't work out a way of fixing this, and had to perform a clean reinstall of OSX.
I was fighting with this problem today for a few hours and ended up trying File -> Invalidate Caches / Restart... and chose the Invalidate/Restart option. Seems to have fixed the Out of Memory error.
Don't know if that will work for you at a later time, but hopefully it helps.
Go to /Applications and do right click on Android Studio > show package contents
Then go to /Contents/bin/studio.vmoptions and change it like this:
-Xms128m
-Xmx800m
-XX:MaxPermSize=350m
-XX:ReservedCodeCacheSize=96m
-XX:+UseCompressedOops
There are couple of ways to handle out of memory in Android Studio:
Clean the Project And Rebuild
Invalidate Caches/Restart -> Sync Project with Gradle files
Restart the PC
Close Android Studio -> Delete .idea folder -> Start the Android
Studio and rebuild.
Still facing the issue, Need proper investigation.
This may be a simple error in your code that Android Studio does not know how to resolve.
Example problem: In my case, within my activity's onCreate function, I wrote binding.root.also{ } and deleted the opening curly bracket of the also scope function. This caused Android Studio to run out of memory and freeze.
Solution: I deleted the also function within Notepad and there were no problems afterwards.
This happened to me when I entered /* to begin commenting out a few lines. And it happened before I could add the */ to close the comment section. Therefore, the entire second half of the file (and beyond) was being commented out. I could not go back to add the needed */ to close the comment, because the "Out of Memory" window kept popping back up before I could do so.
So I closed Android Studio,
opened the same .java file in NotePad,
added the needed * / a few lines below the /*,
saved the file with NotePad,
then reopened it again in Android Studio.
The Out of Memory problem was gone for good.
I also got the same problem in my case, I tried to dump memory and it is reached to 200mb and while opening the studio it is showing the continuous process, because of '.hprof' the file is loading. Finally, I removed the '.hprof' and able to run my project. The .'hprof' file removed from the directory ''
I had the same error recently (Android studio 3) even though I had 16gb Ram + I7700K CPU.
I noticed that it started to appear after I disabled the Virtual Memory Ram because I needed some extra space in my SSD. so I just reactivated it and the problem was solved!
I am developing an Android App in which I use lot of JNI Code.. Recently (from last 2-3 days I am really annoyed by surprise behavior of eclipse) it shows me vague errors as soon as I open my .c file... However errors disappear if I close and reopen the project. See the secreen shot attached. Is it because I just update my eclipse installation (just update of eclipse plugins, I am still on my old Indigo)...
Is it an eclibse bug or something wrong with my setup ?
Solved ????
I tried everything but noting could change the behavior of eclipse.. By this time I knew that I have certainly messed with the project Settings by mistake, since eclipse was behaving well in other projects of same workspace. So I recreated the project manually and finally that solved myproblem...Though the Question is still open for valuable answers I think soon I will get some good answers..
UPDATE
Even eclipse 4.2 release also has this problem.. #frustrating
I found that deleting the project and than reimporting the project to workspace solves the problem. However I also came to knew that deleting .cproject file from the project tree can also fix this problem. Fixing the NDK path (Window -> Preferences -> Android-> NDK) in Eclipse preferences may also solve the problem.
Solution 2 Which may work in few cases...
Right click on the project.
Select Android Tools -> Fix Project Properties
