android - how to correct this error: java.lang.OutOfMemoryError -

-

this code:

public void onpicturetaken(byte[] data, camera camera) {     bitmap foto = bitmapfactory.decodebytearray(data, 0, data.length);     wid = foto.getwidth();     hgt = foto.getheight();      bitmap newimage = bitmap.createbitmap(wid, hgt, bitmap.config.argb_4444);     canvas canvas = new canvas(newimage);     canvas.drawbitmap(foto, 0f, 0f, null);     if (newimage.getwidth() > newimage.getheight()) {         matrix matrix = new matrix();         matrix.postrotate(90);         newimage.createbitmap(newimage, 0, 0, wid, hgt, matrix, true);      } }

this error:

fatal exception: main java.lang.outofmemoryerror @ android.graphics.bitmap.nativecreate(native method) @ android.graphics.bitmap.createbitmap(bitmap.java:689) @ android.graphics.bitmap.createbitmap(bitmap.java:666) @ android.graphics.bitmap.createbitmap(bitmap.java:633) @ com.supratecnologia.activity.camera_activity.onpicturetaken(camera_activity.java:189) @ android.hardware.camera$eventhandler.handlemessage(camera.java:768) @ android.os.handler.dispatchmessage(handler.java:99) @ android.os.looper.loop(looper.java:137) @ android.app.activitythread.main(activitythread.java:5041) @ java.lang.reflect.method.invokenative(native method) @ java.lang.reflect.method.invoke(method.java:511) @ com.android.internal.os.zygoteinit$methodandargscaller.run(zygoteinit.java:793) @ com.android.internal.os.zygoteinit.main(zygoteinit.java:560) @ dalvik.system.nativestart.main(native method)

ost of times happens due large bitmap cross limit of vm heap, need scale down image or lower quality of image.

to scale image use bitmapfactory.options.

bitmap bm = null; bitmapfactory.options options = new bitmapfactory.options(); options.insamplesize = 5; assetfiledescriptor filedescriptor =null; try {     filedescriptor = this.getcontentresolver().openassetfiledescriptor(selectedimage,”r”); } catch (filenotfoundexception e) {     e.printstacktrace(); } finally{     try {         bm = bitmapfactory.decodefiledescriptor(filedescriptor.getfiledescriptor(), null, options);         filedescriptor.close();     } catch (ioexception e) {         e.printstacktrace();     } }

or use bitmap.compress() lower quality of image.

and can follow conversation avoid memory error while loading images in bitmap.
