Eclipse freezes when using “ctrl+space” for Android autocomplete popup

Question

Last week I faced a problem of windows activation and my windows start slow down. After I solved that problem, windows run normally as before but I got Errors in Eclipse for developing android applications.

Everything is OK in Eclipse and I'm using "ctrl+space" in Java Projects is fine, Autocomplete popup is shown and working properly.

But, when I use "ctrl+space" in Android project, autocomplete popup show with several options and eclipse suddenly freeze for a couple of minutes(sometimes more than 3 or 4 minutes). After that I can choose the first option from the popup by hitting enter, but scroll down or choose another option, it's freeze again and wait for another several minutes.

Here is my environment.

Windows 7 (64bit)

Eclipse Juno - build id - 20120614-1722

ADT 22.6.0.v201403010043

JDK-7u51 x64

Here is Eclipse.ini file.

My problem is similar to

But I'm using the same Eclipse on my desktop and laptop. Laptop run normally on Android and working fine. The only problem is on my desktop. So, upgrading to another Eclipse is not the best option to solve (just my opinion). Because I've tried latest Eclipse (Juno), but problem still happened.

I think, some program or file is missing after I repaired windows activation which is something like Eclipse Juno - Constant crash when highlighting anything. Then I update my graphic driver, testing html files, everything work like charm.But that time, I uninstalled some software from my system as Blue Stack, ASUS Smart Doctor, Cheat Engine, GTalk and others...(maybe 7 or 8. don't remember all).

I have no idea which program is blocking or making lag of popping up android autocomplete. I'm using only English Language and not install any other language in my computer, which is like Content Assist (Ctrl + Space) Is Not Working – Eclipse. Because I can use "ctrl+space" in java projects.

Another thing is I cannot hover or highlight on anything in every Projects. Java projects, I can use "ctrl+space" and choose any options from autocomplete popup but cannot hover on some variable, eclipse crash. Android projects, both "ctrl+space" and hover on something cannot use, eclipse hang.

Can anyone suggest me for my problem.

You can try to enlarge the Java heapspace. Maybe that's the failure — Logi24

I have had the exact same issue with my Eclipse. You can start by increasing XXMaxPermSize, though there is the possibility that it could make Eclipse unstable. I haven't had a problem personally, but it came up in the documentation. Usually you have to find the balance between MaxPermSize and the Xms value.

The one thing I see that should be changed right away is that your Xms and Xmx are the same. Due to the way the JVM works, they should never be set to the same value. I suggest either halving Xms or doubling Xmx and see what it does.

Another thing you can try is run it with the -clean argument. You can add it in the .ini or you can put it after the file name under "target" in your shortcut properties.
