OutOfMemoryError when setting ImageView

Question

I am trying to add a few Linearlayouts which every one contains a TextView and an ImageView at runtime.

Everything works but the application crashed when trying to setImageResource. (OutOfMemoryError)

Heres my Activity (relevant part):

my_icon is the name of the drawable in res folder (the name is different in every loop (name comes from xml).

// looping through all item nodes <item>
 for (int i = 0; i < nl.getLength(); i++) {
 Element e = (Element) nl.item(i);
 String my_icon = parser.getValue(e, "my_icon"); // my_icon child value
 int my_count = Integer.parseInt(parser.getValue(e, "my_count")); // my_count child value
 String my_text = parser.getValue(e, "my_text"); // my_text child value
 //Create Child-Views
 LinearLayout tempLinearLayout = new LinearLayout(AnleitungActivity.this);
 linearLayout.addView(tempLinearLayout);
 tempLinearLayout.setOrientation(LinearLayout.HORIZONTAL);
 ViewGroup.LayoutParams params = tempLinearLayout.getLayoutParams();
 params.width = ViewGroup.LayoutParams.MATCH_PARENT;
 params.height = 240;
 tempLinearLayout.setBackgroundColor(ContextCompat.getColor(AnleitungActivity.this, R.color.anleitung_kachel_hintergrundfarbe));
 ViewGroup.MarginLayoutParams marginParams = (ViewGroup.MarginLayoutParams) tempLinearLayout.getLayoutParams();
 marginParams.setMargins(0,5,0,0); //für die Margin-Werte brauchen wir extra MarginLayoutParams...
 tempLinearLayout.setLayoutParams(params); //layoutParams setzen
 tempLinearLayout.setLayoutParams(marginParams); //MarginLayoutParams setzen
 TextView tv = new TextView(AnleitungActivity.this);
 tempLinearLayout.addView(tv);
 LinearLayout.LayoutParams tvParams = new LinearLayout.LayoutParams(70, ViewGroup.LayoutParams.MATCH_PARENT,1f);
 tv.setLayoutParams(tvParams);
 tv.setText(transformText(my_text));
 tv.setTextSize(17);
 tv.setPadding(5,0,0,0);
 tv.setTextColor(ContextCompat.getColor(AnleitungActivity.this, R.color.anleitung_text_farbe));
 ImageView imageView = new ImageView(AnleitungActivity.this);
 tempLinearLayout.addView(imageView);
 imageView.getLayoutParams().height = dp2px(getResources(), 60);
 imageView.getLayoutParams().width = dp2px(getResources(), 60);
 imageView.setImageResource(getDrawableRessorceIdByName(AnleitungActivity.this, removeFileExtensionFromString(my_icon)));
 }

help method

 public String removeFileExtensionFromString(String str){
 return str.substring(0, str.indexOf("."));
}

• an_droid_dev: you can find this question here : stackoverflow.com/questions/33279223/…
• skm: Solved...Images were too big...just reduced the sizes.
• vsatkh: I am not sure about this method "getDrawableRessorceIdByName", you might to use this method instead "Resources.getIdentifier" or probably you already use it.
• skm: It´s working, read my comment before your´s

Answer 1

There are two ways to solve this problem.

1.Try to reduce the size of image [ HIGHLY RECOMMENDED]

• You can visit tinyJPG.com to reduce the size and also maintain the quality of image.

• Make sure you didn't use very high resolution image as they are not useful.

2.Use largeHeap [NOT RECOMMENDED]

• Add largeHeap="true" in your Manifest.

• This may reduce the performance of app a little bit.
