Android: Does a bitmap created by my app have to be stored and scanned before I can pass it as an implicit intent to other apps?
android,android-intent,android-image,android-bitmap,android-implicit-intent
No, you dont need to save that image anywhere. Just get the filepath from the Bitmap: String path = Images.Media.insertImage(context.getContentResolver(), bitmap,"abcd", null); then get a valid Uri from it: Uri image = Uri.parse(path); and add this Uri to your Intent like this: intent.putExtra(Intent.EXTRA_STREAM, image); Done!...

Issue in Posting Image on php Server in android
encodeToString is not a function in BitmapFactory. You should encode to base64 in a different way. I would like to suggest this answer
Formats supported by BitmapFactory.decodeByteArray(…)
Yes, it's reasonable to assume (a bit more so if you take a peek at the source code of AOSP). The JNI native methods for BitmapFactory are in BitmapFactory.cpp. https://github.com/android/platform_frameworks_base/blob/master/core/jni/android/graphics/BitmapFactory.cpp Since both BitmapFactory.decodeByteArray() and the BitmapDrawable(InputStream) constructor end up calling doDecode(), and since this constructor is used when loading resources...
