注意
Android6.0系統(tǒng)默認(rèn)為targetSdkVersion小于23的應(yīng)用默認(rèn)授予了所申請(qǐng)的所有權(quán)限，所以如果你以前的APP設(shè)置的targetSdkVersion低于23，在運(yùn)行時(shí)也不會(huì)崩潰，
但這也只是一個(gè)臨時(shí)的救急策略，用戶還是可以在設(shè)置中取消授予的權(quán)限蚁趁。
android {
compileSdkVersion 23
buildToolsVersion "23.0.1"
defaultConfig {
applicationId "com.money.app
minSdkVersion 18
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}
Camera權(quán)限
if (ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CAMERA}, 1);
}
存儲(chǔ)的權(quán)限
if (ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this,
new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 2);
}
授權(quán)后的回調(diào)onRequestPermissionsResult
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions,
int[] grantResults) {
switch (requestCode) {
case 1:
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
checkStorgePermission();
} else {
mHasPermission = false;
}
break;
case 2:
if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
mHasPermission = true;
} else {
mHasPermission = false;
}
break;
}
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
注意這里case 中的1和2，是Camera和存儲(chǔ)權(quán)限的requestCode，這里來(lái)判斷是哪個(gè)權(quán)限申請(qǐng)凯旋。
