android 6.0适配（总结）

6.0的适配主要是权限：

权限的分组：

普通权限：也就是正常权限，是对手机的一些正常操作，对用户的隐私没有太大影响的权限，比如手机的震动，网络访问，蓝牙等权限，这些权限会在应用被安装的时候默认授予，用户不能拒绝，也不能取消

危险权限：其实就是运行中需要处理的权限，也是我们最需要注意的权限，这些权限会关系到用户的隐私或影响到其他应用的运行

权限的申请：

@RequiresApi(api = Build.VERSION_CODES.M)
private void checkPermission() {
    String[] permissions = new String[]{
            Manifest.permission.ACCESS_FINE_LOCATION,
            Manifest.permission.RECORD_AUDIO,
            Manifest.permission.READ_PHONE_STATE,
            Manifest.permission.CAMERA,
            Manifest.permission.READ_EXTERNAL_STORAGE,
            Manifest.permission.WRITE_EXTERNAL_STORAGE};

    ActivityCompat.requestPermissions(this, permissions, 1000);
}

@RequiresApi(api = Build.VERSION_CODES.M)
@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    for (String permission : permissions) {
        if (PermissionUtils.isGranted(permission)) {
            Log.i("permission", "同意的权限：" + permission);
        } else {
            //已拒绝
            finish();
            Log.i("permission", "已拒绝的权限：" + permission);
            if (!ActivityCompat.shouldShowRequestPermissionRationale(this, permission)) {
                //禁止后不再询问
                Log.i("permission", "禁止后不再询问的权限：" + permission);
            }
        }
    }
}

/**
 * Return whether <em>you</em> have granted the permissions.
 *
 * @param permissions The permissions.
 * @return {@code true}: yes<br>{@code false}: no
 */
public static boolean isGranted(final String... permissions) {
    for (String permission : permissions) {
        if (!isGranted(permission)) {
            return false;
        }
    }
    return true;
}

private static boolean isGranted(final String permission) {
    return Build.VERSION.SDK_INT < Build.VERSION_CODES.M
            || PackageManager.PERMISSION_GRANTED
            == ContextCompat.checkSelfPermission(Utils.getApp(), permission);
}

 Android 6.0中，还有两个特殊权限的处理：

• 设置悬浮窗： SYSTEM_ALERT_WINDOW

• 修改系统设置：WRITE_SETTINGS

 修改系统设置权限的授权 WRITE_SETTINGS，与其他权限不同，而是使用startActivityForResult，启动系统设置的授权界面来申请

private void requestWriteSettings() {
    try {
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {
            //修改系统设置，正常处理逻辑
        } else {
            if (!Settings.System.canWrite(this)) {
                Intent intent = new Intent(Settings.ACTION_MANAGE_WRITE_SETTINGS);
                intent.setData(Uri.parse("package:" + getPackageName()));
                startActivityForResult(intent, REQUEST_CODE_WRITE_SETTINGS);
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

@RequiresApi(api = Build.VERSION_CODES.M)
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == REQUEST_CODE_WRITE_SETTINGS) {
        if (Settings.System.canWrite(this)) {
            Log.i("permission", "onActivityResult write settings granted");            
             //修改系统设置，正常处理逻辑        
           }
    }
}
