Try each step separately:
- Restart Eclipse
- Clean project and rebuild
- Create a new project and try it if the problem persists, if no move copy project to other folder, delete project from workspace , create new project same name and copy java, xml etc. files to new project
- Close Eclipse, backup folder c:\Users\myName\workspace\.metadata and delete it. Restart Eclipse try again import project to workspace
- Re-installing the Android Developer Tools
- Re-installing Eclipse - rename old folder with Android to Android_old, create new folder C:\Program Files\Android and copy new Eclipse with sdk into new folder
- Created a new project importing from the file system
- Created a new project from subversion
Problem: erroneous entry of id
Solution: @+id/
<RadioButton android:id="idRadio"
android:text="My radio button"/>
Solution: @+id/
<RadioButton android:id="@+id/idRadio"
android:text="My radio button"/>
Try this code with CursorLoader:
Uri uri = getIntent().getData();
// DEPRECATED
Cursor cursor = managedQuery(uri, null, null, null, null);
// WORKING - loadInBackground() preventing freezing of app
Cursor cursor = new CursorLoader(getApplicationContext(),uri, null, null, null, null).loadInBackground();
Try this solution:
String DATA = "Html text....bla bla bla. Hellou world! čšřžěéá";
String HEADERHTML =
"<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">"
+"<html> <head> <meta http-equiv="content-type" content="text/html; charset=utf-8">"
+"</head> <body>";
String FOOTERHTML = "</body></html>";
WebView mWebView.loadData(HEADERHTML+DATA+FOOTERHTML,"text/html; charset=UTF-8",null);
Where file(s) does eclipse store Java code style settings to?
If you need copy any old templates to the new workspace.
You can edit the Eclipse Templates from menu Window - Preferences - Java - Editor - Templates.
