我在自己和朋友的手機上，沒有出現這個問題。
android.database.sqlite.SQLiteException: no such table: password: , while compiling: SELECT username, password FROM password WHERE (host == ?) at android.database.sqlite.SQLiteCompiledSql.native_compile(Native Method) at android.database.sqlite.SQLiteCompiledSql.(SQLiteCompiledSql.java:68) at android.database.sqlite.SQLiteProgram.compileSql(SQLiteProgram.java:143) at android.database.sqlite.SQLiteProgram.compileAndbindAllArgs(SQLiteProgram.java:361) at android.database.sqlite.SQLiteProgram.(SQLiteProgram.java:127) at android.database.sqlite.SQLiteProgram.(SQLiteProgram.java:94) at android.database.sqlite.SQLiteQuery.(SQLiteQuery.java:53) at android.database.sqlite.SQLiteDirectCursorDriver.query(SQLiteDirectCursorDriver.java:47) at android.database.sqlite.SQLiteDatabase.rawQueryWithFactory(SQLiteDatabase.java:1684) at android.database.sqlite.SQLiteDatabase.queryWithFactory(SQLiteDatabase.java:1569) at android.database.sqlite.SQLiteDatabase.query(SQLiteDatabase.java:1525) at android.database.sqlite.SQLiteDatabase.query(SQLiteDatabase.java:1605) at android.webkit.WebViewDatabase.getUsernamePassword(WebViewDatabase.java:990) at android.webkit.BrowserFrame.handleMessage(BrowserFrame.java:589) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:137) at android.webkit.WebViewCore$WebCoreThread.run(WebViewCore.java:950) at java.lang.Thread.run(Thread.java:856)
我只用了webview，沒有用sqlite，但是出現了了這個問題。
網上搜了一下，問題肯能出在
context.deleteDatabase("webview.db"); context.deleteDatabase("webviewCache.db");也是網上關於刪除緩存webview的代碼。
參考：

http://stackoverflow.com/questions/8663227/android-webview-throws-sqliteexception
覺得這個刪除緩存的方法不太實用，我只是想在某個點去刪除所有的緩存，這個方法不太適合：
@Overridepublicvoid onPageFinished(WebView view,String url){
super.onPageFinished(view, url); view.clearCache(true);
