Question

我在我的manisfest中拥有api 22的权限 - ：

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission
    android:name="android.permission.ACCESS_FINE_LOCATION"
    android:maxSdkVersion="22" />
<uses-permission
    android:name="android.permission.ACCESS_COARSE_LOCATION"
    android:maxSdkVersion="22" />
<uses-permission
    android:name="android.permission.READ_CONTACTS"
    android:maxSdkVersion="22" />
<uses-permission
    android:name="android.permission.WRITE_CONTACTS"
    android:maxSdkVersion="22" />
<uses-permission
    android:name="android.permission.READ_EXTERNAL_STORAGE"
    android:maxSdkVersion="22" />

运行时检查权限以及api 23 +：

private void requestGpsPermission() {
    if (ContextCompat.checkSelfPermission(this,
            Manifest.permission.READ_CONTACTS)
            != PackageManager.PERMISSION_GRANTED ||
            ContextCompat.checkSelfPermission(this,
            Manifest.permission.WRITE_CONTACTS)
            != PackageManager.PERMISSION_GRANTED)
        ActivityCompat.requestPermissions(this, new String[]{
                Manifest.permission.READ_CONTACTS,
                Manifest.permission.WRITE_CONTACTS}, 1);

    if (ContextCompat.checkSelfPermission(this,
            Manifest.permission.ACCESS_FINE_LOCATION)
            != PackageManager.PERMISSION_GRANTED ||
            ContextCompat.checkSelfPermission(this,
                    Manifest.permission.ACCESS_COARSE_LOCATION)
                    != PackageManager.PERMISSION_GRANTED)
        ActivityCompat.requestPermissions(this, new String[]{
                Manifest.permission.ACCESS_FINE_LOCATION,
                Manifest.permission.ACCESS_COARSE_LOCATION}, 2);

    if (ContextCompat.checkSelfPermission(this,
            Manifest.permission.READ_EXTERNAL_STORAGE)
            != PackageManager.PERMISSION_GRANTED)
        ActivityCompat.requestPermissions(this, new String[]{
                Manifest.permission.READ_EXTERNAL_STORAGE}, 3);
}

我仍然有错误：

我正在尝试在Android 6.0设备中运行该应用。关于如何解决它的任何想法？

Answer 1

经过2天的努力，我终于成功了。我错过了以下方法：

1 @Override
2 public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {
3     // If request is cancelled, the result arrays are empty.
4     if (grantResults.length > 0
5             && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
6         // permission granteed
7        P.toast(this, "permission granteed :-)");
8         getHeaders();
9     } else {
10        // permission denied
11        P.toast(this, "permission denied :-(");
12    }
13    return;
14}

我也必须修改验证方法，所以如果我已经拥有权限它从那里调用getHeaders（）：

1 private void requestGpsPermission() {
2     if (
3             ContextCompat.checkSelfPermission(this,
4                     Manifest.permission.READ_CONTACTS)
5                     != PackageManager.PERMISSION_GRANTED ||
6                     ContextCompat.checkSelfPermission(this,
7                             Manifest.permission.ACCESS_FINE_LOCATION)
8                             != PackageManager.PERMISSION_GRANTED ||
9                     ContextCompat.checkSelfPermission(this,
10                            Manifest.permission.READ_EXTERNAL_STORAGE)
11                            != PackageManager.PERMISSION_GRANTED
12            ) {
13        ActivityCompat.requestPermissions(this, new String[]{
14                Manifest.permission.READ_CONTACTS,
15                Manifest.permission.ACCESS_FINE_LOCATION,
16                Manifest.permission.READ_EXTERNAL_STORAGE
17        }, 1);
18    } else {
19        getHeaders();
20    }
21}

请注意，我在第一个mehotd的第8行和第二个mehotd的第19行调用相同的方法。

为什么在询问用户后权限被拒绝？
