The aim is to change heap size of JVM. Under the  /usr/share/tomcat6/bin , there is a file name as catalina.sh. In the file you can write CATALINA_OPTS="-Xms256m -Xmx256m" at the 2nd line and then restart the tomcat. To do that, (I supposed that you have a root right. If not , type sudo -s ) First of all, go to the tomcat6 bin directory and stop it.  ex. /etc/init.d/tomcat6 stop Then, change the right of the catalina.sh file as root. Here is;  chown  gunay /usr/share/tomcat6/bin/catalina.sh Important: I have used in ubuntu machine and tomcat6 is ubuntu's tomcat not a standalone version. At the end, you can change file rights as tomcat6 and then start the server. /etc/init.d/tomcat6 start

 Error: Pop-up keyboard and textedit selected when the activity is started. The first solution is ;   This is hide keyboard and also nothing is not selected or focused.   Use this attributes in your layout tag in XML file: android : focusable = "true" android : focusableInTouchMode = "true"   The second solution is ; Put a ndroid:windowSoftInputMode="stateHidden" in activity in the AndroidManifest.xml   This is only hide keyboard but the textedit is selected or focused.   <activity android:name="com.test.login" android:windowSoftInputMode="stateHidden" android:screenOrientation="portrait" />

you can apply styles as themes on an activity level or application level. if you apply a theme on an activity level then all widgets within that activity will inherit from that theme. to do so, open the AndroidManifest.xml and go the <activity> tag and add the android:theme attribute:   <activity android:name=".StylesDemo" android:label="@string/app_name" android:theme="@style/BlueLabel">   to apply a theme on the application level so that the style will be applied to all activities within your application, open the AndroidManifest.xml and go the <application> tag and add the android:theme attribute:   <application android:icon="@drawable/icon" android:label="@string/app_name" android:theme="@style/BlueLabel"> to set the theme of an activity programmatically call this line in the onCreate method   this.setTheme(R.style.BlueLabel);

Place the TTF file in the ./assets directory (create it if it doesn’t exist yet). We’re going to use a basic layout file with a TextView, marked with an id of “custom_font” so we can access it in our code.   <? xml   version = "1.0"   encoding = "utf-8" ?>    < LinearLayout   xmlns:android = "http://schemas.android.com/apk/res/android"                   android:orientation = "vertical"                   android:layout_width = "fill_parent"                   android:layout_height = "fill_parent"             >            < TextView                 android:id = "@+id/custom_font"                 android:layout_width = "fill_parent"                 android:layout_height = "wrap_content"                 android:text = "This is the Chantelli Antiqua font."                 />       </ LinearLayout >      Open your main activity file and insert this into t

Creating Three Sets of Graphics Because of the aforementioned screen resolution/size issue, Android recommends creating three sets of graphics for: Hi Density Screens Medium Density Screens Low Density Screens This will keep your design from getting crunked up when it’s displayed on various screen sizes. The grid below shows the various screen sizes and resolutions you use for your Photoshop files: I know it’s a lot. But if you’re creating your design using vector shape layers, the re-sizing process shouldn’t be too painful. The key is to design for the smallest screen first, and then size up for larger screens.
