apk dynamic application permission

1. After Android 6.0, you not only need to apply for permissions in AndroidManifest.xml, but also need to apply for permissions in the code, giving a packaged interface, which can be directly modified and used in the code.
2. After adding, a pop-up window for permission application will appear

    /**
     * Android6.0之后需要动态申请权限
     */
    private void requestPermission() {
    	// 这个判断可以不要，目前6.0的手机基本上没有了
        if (Build.VERSION.SDK_INT >= 23) {
            ArrayList<String> permissionsList = new ArrayList<>();
            String[] permissions = {
            		// 在这块申请加上权限的名字，就是AndroidManifest.xml中的权限名字
                    Manifest.permission.ACCESS_COARSE_LOCATION,
                    Manifest.permission.ACCESS_FINE_LOCATION,
            };

            for (String perm : permissions) {
                if (PackageManager.PERMISSION_GRANTED != checkSelfPermission(perm)) {
                    permissionsList.add(perm);
                    // 进入到这里代表没有权限.
                }
            }

            if (!permissionsList.isEmpty()) {
                String[] strings = new String[permissionsList.size()];
                requestPermissions(permissionsList.toArray(strings), 0);
            }
        }
    }
