我从图库中选择700kb图像并收到IllegalArgumentException。我将其与recycle()
的ussage链接以节省一些内存。当我开始得到OutOfMemoryError时,它会出现实际问题,因此我认为我必须使用回收。我是以错误的方式调用它还是有一些规则如何使用它?
错误:

pho1.setImageBitmap(bitmap);

ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 90, stream);
byte[] byte_arr = stream.toByteArray();
photo1 = Base64.encodeToString(byte_arr, Base64.DEFAULT);
bitmap.recycle();
bitmap = null;
byte_arr=null;
try {
stream.close();
} catch (IOException e) {

答案 0 :(得分:0)
请删除bitmap.recycle();言。
