Memory exception

I have the opportunity to view my application in different languages ​​- English, Tamil and Hindi. I used customtextview where the font is installed depending on what language the user wants.

I get a memory exception when the application is used for a while. Is there any direct effect of setting the font for all text views in the application?

Attached a CustomTextView code snippet extending Textview:

public L10nTextView(Context context, AttributeSet attrs) { super(context, attrs); this.ttfName = ttfFileName; init(); } private void init() { if (ttfName != null) { setTypeface(MyApplication.typeFace); } else { setTypeface(null); } }

Error Log:

Without the localization function, my application works fine and does not crash.

base_layout.xml:

  <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/header_bar_layout" android:visibility="visible" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/header_bar" android:visibility="visible" android:layout_width="fill_parent" android:layout_height="wrap_content"> <ImageView android:id="@+id/header_click" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/before" android:layout_alignParentRight="true" /> <ProgressBar android:id="@+id/prg_bar" android:layout_toLeftOf="@id/header_click" android:layout_width="25dip" android:layout_height="25dip" android:layout_centerVertical="true" android:visibility="gone" /> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/logo_layout" android:orientation="horizontal" android:layout_alignParentLeft="true" android:layout_width="wrap_content" android:layout_height="wrap_content" android:visibility="visible"> <ImageView android:id="@+id/logo_bar" android:layout_alignParentLeft="true" android:layout_height="wrap_content" android:src="@drawable/logo_bar" android:layout_width="wrap_content" /> </LinearLayout> <LinearLayout android:id="@+id/rating" android:orientation="horizontal" android:layout_alignParentLeft="true" android:layout_width="wrap_content" android:layout_height="wrap_content" android:visibility="invisible"> <ImageView android:id="@+id/rate_us" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/rate_us" /> <ImageView android:id="@+id/like_us" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/fb_like_us" /> <ImageView android:id="@+id/follow_us" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/twitter_follow_us" /> </LinearLayout> </RelativeLayout> </LinearLayout>

I install the language when the language is changed, restarts my application. But the memory is not released, and every time my application opens, it only increases when the application crashes due to low memory.

Setlocale method to change the language:

  public void setLocale(String languageLocaleToLoad) { Locale locale = new Locale(languageLocaleToLoad); Locale.setDefault(locale); android.content.res.Configuration config = new android.content.res.Configuration(); config.locale = locale; getResources().updateConfiguration(config, getResources().getDisplayMetrics()); }

I also found out that the size of the native heap is constantly increasing when the language changes and, finally, the application crashes.

Memory Analysis Tool (MAT) helps you find out where your memory goes. Often an accident does not occur exactly where the real problem exists.

http://eclipse.org/mat/

You can unload memory directly from the DDMS view in Eclipse (use the heap of updates button and then start garbage collection). It may take a little time to understand the tool, but it is important for your arsenal.

By the way, I had an exclusive memory issue related to the language version. My problem was that I reloaded the activity in order to change the locale, and in one case she was not able to load the new locale and continue to reboot until it was exhausted.
