问题 I am writing an App which does the following with a given String str: encode(encrypt(encode(stringToBytearray(str)))); The Server receives the Base64 encoded String, which is then decoded -> decrypted -> decoded, to get the sent String str from the App. Unfortunately it doesnt work for all Strings, long Strings lead to a long Base64 String and my Server throws the following Exception: Exception in thread "main" java.lang.IllegalArgumentException: Illegal base64 character 5b at java.util

问题 I need to implement conversion tracking on my android app using firebase analytics. In order to do that I will add some UTM parameters to my links, and that links will open a screen on my android app (using deep linking) and then I think I will need to send those parameters to Firebase. What I want to know is what is the right/common approach to do this? Should I parse the URL on opening the app, save the UTM parameters and send them later when a conversion occurs? How shold I send them to

问题 So i am drawing a Point at a certain ... well ... point of the screen that is then moving around. My Vertex Shader looks like this. private final String vertexShaderCode = "attribute vec4 vPosition;" + "uniform mat4 Projection; \n" + "uniform mat4 ModelView; \n" + "void main() {" + " gl_Position = Projection * ModelView * vPosition;" + " gl_PointSize = 900.0; " + "}"; What i am trying to achive is to then render a circle around the position of this one vertice. For that i am using the

问题 I am trying to backup the application data of my android app on Google Drive. Therefore I request access to the https://www.googleapis.com/auth/drive.appdata, https://www.googleapis.com/auth/drive.file scopes using the google_sign_in package. I created a project on the Google Developer Console, enabled the Drive API and added the scopes to the OAuth Consent Screen and added an OAuth Client ID with the package name and the SHA-1 of the debug key. The application works fine if I don't request
