constraintlayout 사용 안 하는데 No package ID ff found for ID 0xffffffff 나올 경우 해결

로그에 No package ID ff found for ID 0xffffffff 나올 경우 해결.

대부분 constraintlayout 버전을 올리라는 얘기밖에 없다

build.gradle 

implementation 'androidx.constraintlayout:constraintlayout:2.0.0-beta3'

그런데 나는 constraintlayout을 사용 안 하는데?

찾아보니 이부분에서 나타난 문제였다

TypedArray ta = context.obtainStyledAttributes(-1, R.styleable.themeTextcolor);

-1 부분을 null로 바꾸면 에러 로그가 생기지 않는다.

TypedArray ta = context.obtainStyledAttributes(null, R.styleable.themeTextcolor);

No such property: variantConfiguration for class:

After upgrading gradle 4.0.0 app build failed with error message:

No such property: variantConfiguration for class: com.android.build.gradle.internal.variant.ApplicationVariantData

is there any way to migrate gradle ?

android.applicationVariants.all { variant ->
        variant.outputs.all {
            def buildType = variant.variantData.variantConfiguration.buildType.name
            ...

        }
    }

app level gradle file

dependencies {
        classpath 'com.android.tools.build:gradle:4.0.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }

android gradle migration

In the last gradle Relase ApplicationVariant implement BaseVariant

Instead of

def buildType = variant.variantData.variantConfiguration.buildType.name

Should be

def buildType = variant.buildType.name

Java - counting specific words

https://codereview.stackexchange.com/questions/73486/counting-five-specific-words-in-a-file

Here's a better, more efficient and compact way:

    String path = "C:/Users/n/Desktop/Text.txt";

    List<String> targetList = Arrays.asList("a", "the", "bird", "animal", "is");
    Map<String, Integer> counts = new HashMap<>(targetList.size());
    for (String word : targetList) {
        counts.put(word, 0);
    }

    for (String line : Files.readAllLines(Paths.get(path))) {
        for (String word : line.replaceAll("[!?.,]", "").toLowerCase().split("\\s+")) {
            Integer count = counts.get(word);
            if (count != null) {
                counts.put(word, count + 1);
            }
        }
    }

    System.out.print(counts.get(targetList.get(0)));
    for (int i = 1; i < targetList.size(); ++i) {
        String word = targetList.get(i);
        System.out.print(" " + counts.get(word));
    }
    System.out.println();

The improvements and corrections:

• It's good to define constants like the path high up in a file where they are easy to change and easy to change, without having to read into the details of the code
• It's simpler to write paths with forward slashes
• Use interface type like List when defining a list instead of implementation type like ArrayList
• Since it seems you're only interested in a specific set of words:
  • I put them in a list for ordering
  • ... then initialized the map of counts to all 0 values
• Instead of building a list of words, it's more efficient to do the counting at the same time as you read the words. This will save you both storage and processing time
• When you do line.replaceAll("[!?.,]", ""), the operation is not performed on line, as strings in Java are immutable. The result with the characters removed is returned
• The same goes for a line.split("\\s+") statement you had. If you don't save the result of the operation, then it's completely pointless
