In this case, all parameters are set incorrectly.

The main common errors are the parameter settings of the following two methods:

Camera. Parameters parameters = mCamera. getParameters ();

Parameters. setPictureSize (1600,120 0 );

Parameters. setPreviewSize (w, h );

How can we set these two parameters?

First, let's take a look at the data acquisition and processing to see if these two methods can pass in those parameters.

List PictureSizes = parameters. getSupportedPictureSizes ();
Int length = pictureSizes. size ();
For (int I = 0; I <length; I ++ ){
Log. e ("TAG", "SupportedPictureSizes:" + pictureSizes. get (I). width + "x" + pictureSizes. get (I). height );
}

List PreviewSizes = parameters. getSupportedPreviewSizes ();
Length = previewSizes. size ();
For (int I = 0; I <length; I ++ ){
Log. e ("TAG", "SupportedPreviewSizes:" + previewSizes. get (I). width + "x" + previewSizes. get (I). height );
}

We can see through the log

17:43:17 05-21. 550: E/= (21262 ): ==w = 1920 ========= h = 1080 hide the resolution corresponding to the Return key of my mobile phone

Therefore, the parameters in these two methods must correspond to the above.

17:47:43 05-21. 575: E/= (21262 ): ==w = 1794 ========= h = 1080 display the resolution of the Return key

My problem is that the use of the glory 6 mobile return key and home are both in the screen, resulting in a high resolution of less than 1920*1080. The error is actually caused by 1794*1080.
