[Phonegap+sencha Touch] Mobile development 30, PHONEGAP camera plug-in several issues

<span style= "FONT-SIZE:14PX;" >navigator.camera.getpicture (function (URI) {    //Get shot Picture path}, function (Err) {}, {    quality:70,    Allowedit:true,//finish the cropping edit    targetwidth:250,    targetheight:250,    destinationtype: navigator.camera.destinationtype.file_uri,//return URI    sourcetype:navigator.camera.picturesourcetype.camera,// Photo    savetophotoalbum:true});</span>

PhoneGap Camera plugin, there are several problems on Android system

1, do not get the true path of the photos taken , specific view blog "Mobile Development 29 Android Navigator.camera.getPicture get pictures of the true path"

2, Targetwidth or targetheight more than 512 pixels , the photo and crop, theapp will crash , or the app does not respond (online Some people say there are 256 pixels, my Meizu MX3 test is 512 pixels)

3, only in targetwidth = = Targetheight time, cut the picture will limit the proportion of 1:1; otherwise, you cannot limit the length and width of the cropping graph , you can adjust any. And we sometimes have to limit the length-to-width ratio of the cropped image.

4, if the Targetwidth and Targetheight are set to 250*250, and the actual clipping resolution is only 100*100, the cropped picture will have black edge .

Workaround:

1, the first problem, the solution to see the blog "Mobile Development 29 Android Navigator.camera.getPicture get pictures of the true path"

2. The second, third and fourth issues are improved as follows:

into the plugin directory, locate this file, Org.apache.cordova.camera\src\android\cameralauncher.java
