android7.0实现分享图片到朋友圈功能

本文实例为大家分享了android实现分享图片到朋友圈功能的具体代码，供大家参考，具体内容如下

在Android7.0中，系统对scheme为file://的uri进行了限制，所以通过这种uri来进行分享的一些接口就不能用了，比如使用代码来调用分享朋友圈的接口。

此时就得使用其他的URI scheme来代替 file://，比如MediaStore的 content://。直接上代码：

private static boolean checkInstallation(Context context, String packageName) {
  try {
   context.getPackageManager().getPackageInfo(packageName, PackageManager.GET_ACTIVITIES);
   return true;
  } catch (PackageManager.NameNotFoundException e) {
   return false;
  }
 }

 public static void shareToWeChat(View view, Context context) {
  // TODO: 2015/12/13 将需要分享到微信的图片准备好
  try {
   if (!checkInstallation(context, "com.tencent.mm")) {
    SnackBarUtil.show(view, R.string.share_no_wechat);
    return;
   }
   Intent intent = new Intent();
   //分享精确到微信的页面，朋友圈页面，或者选择好友分享页面
   ComponentName comp = new ComponentName("com.tencent.mm", "com.tencent.mm.ui.tools.ShareToTimeLineUI");
   intent.setComponent(comp);
   intent.setAction(Intent.ACTION_SEND_MULTIPLE);
   intent.setType("image
  ".jpg",   
  storageDir  
 );

 // Save a file: path for use with ACTION_VIEW intents
 mCurrentPhotoPath = "file:" + image.getAbsolutePath();
 return image;
}

static final int REQUEST_TAKE_PHOTO = 1;

private void dispatchTakePictureIntent() {
 Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
 // Ensure that there's a camera activity to handle the intent
 if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
  // Create the File where the photo should go
  File photoFile = null;
  try {
   photoFile = createImageFile();
  } catch (IOException ex) {
   // Error occurred while creating the File
   ...
  }
  // Continue only if the File was successfully created
  if (photoFile != null) {
   Uri photoURI = FileProvider.getUriForFile(this,
      "com.example.android.fileprovider",
      photoFile);
   takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
   startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);
  }
 }
}

还要在manifest中声明这个FileProvider

在res/xml/文件夹下新建文件file_paths.xml：
