b: ok, you are debugging, which line of code has a problem, take a look at this compressImageFromFile, anyway the bitmap finally is null before the code above is my code, I am a bitmap can be generated

CodePudding user response:

Android 7.0 cannot be used directly after the uri. Fromfile refer to this, there are other configuration items baidu the

 
Uri the Uri=null; 
If (Build) VERSION) SDK_INT & gt;=Build. VERSION_CODES. N) {
Uri=FileProvider. GetUriForFile (this, getPackageName () + ". FileProvider ", the file). 
} else {
Uri=uri. FromFile (file); 
} 

CodePudding user response:

, step by step, the best way is to debug, go see compressed bitmap method in which one has a problem, if the file exists, the file is valid, whether high wide to 0, whether to have permissions, and so on,

CodePudding user response:

Version of the estimation is permission problems, pay attention to the phone after 9.0,
