Question

来自AudioPlayService类onCreate（）我在第168行调用以下代码.-

line168- CustomAuxEffectStats aa = CustomAuxEffectStats.getInstance();
    if (aa == null) {
        createCustomAuxEffect();
    }

CustomAuxEffectStats类 -

public class CustomAuxEffectStats implements Serializable {
    private static CustomAuxEffectStats customAuxEffectStats = null;
    public static int CustomPresetID = -100;

    public static final int DEFAULT_BASS_BOOST_STRENGTH = 900;

    private boolean isEnabled;

    private int numBands;
    private int actualNumPreset;

    private short selectedPreset;
    private short minBandLevel;
    private short maxBandLevel;
    private short bassboostStrength;

    private short[] bandLevels;

    private String[] bandFreq;
    private String[] presetNames;

    private CustomAuxEffectStats(short curPreset, String[] presetNamesArr, String[] bandFreqs, short[] bandLevelRange, short[] bandlevels, boolean isEnabled) {
        this.isEnabled = isEnabled;
        selectedPreset = curPreset;

        minBandLevel = bandLevelRange[0];
        maxBandLevel = bandLevelRange[1];

        numBands = bandlevels.length;

        bandFreq = bandFreqs;

        actualNumPreset = presetNamesArr.length - 1;
        CustomPresetID = presetNamesArr.length;

        presetNames = presetNamesArr;

        this.bandLevels = bandlevels;
        bassboostStrength = 1000;
    }

    public static CustomAuxEffectStats getInstance() {
        return customAuxEffectStats;
    }

    public static CustomAuxEffectStats createInstance(short curPreset, String[] presetNamesArr, String[] bandFreqs, short[] bandLevelRange, short[] bandlevels, boolean isEnabled) {
        if (customAuxEffectStats == null) {
            customAuxEffectStats = new CustomAuxEffectStats(curPreset, presetNamesArr, bandFreqs, bandLevelRange, bandlevels, isEnabled);
        }
        return customAuxEffectStats;
    }

    public boolean isEnabled() {
        return isEnabled;
    }

    public void setEnabled(boolean isEnabled) {
        this.isEnabled = isEnabled;
    }

    public int getNumBands() {
        return numBands;
    }

    public void setNumBands(int numBands) {
        this.numBands = numBands;
    }

    public short getSelectedPreset() {
        return selectedPreset;
    }

    public void setSelectedPreset(short selectedPreset) {
        this.selectedPreset = selectedPreset;
    }

    public short getMinBandLevel() {
        return minBandLevel;
    }

    public void setMinBandLevel(short minBandLevel) {
        this.minBandLevel = minBandLevel;
    }

    public short getMaxBandLevel() {
        return maxBandLevel;
    }

    public void setMaxBandLevel(short maxBandLevel) {
        this.maxBandLevel = maxBandLevel;
    }

    public short[] getBandLevels() {
        return bandLevels;
    }

    public void setBandLevels(short[] bandLevels) {
        this.bandLevels = bandLevels;
    }

    public String[] getBandFreq() {
        return bandFreq;
    }

    public void setBandFreq(String[] bandFreq) {
        this.bandFreq = bandFreq;
    }

    public static int getCustompresetid() {
        return CustomPresetID;
    }

    public short getBassBoostStrength() {
        return bassboostStrength;
    }

    public void setBandLevel(short band, short progress) {
        bandLevels[band] = progress;
    }

    public short getbandLevel(short band) {
        return bandLevels[band];
    }

    public int getNumberOfPresets() {
        return actualNumPreset;
    }

    public String[] getPresetNames() {
        return presetNames;
    }

    public void setPresetNames(String[] presetNames) {
        this.presetNames = presetNames;
    }

    public void setBassboostStrength(short bassboostStrength) {
        this.bassboostStrength = bassboostStrength;
    }
}

当我运行我的应用程序时，这总是在kitkat（dalvik运行时）设备上崩溃。但它在L +（ART）设备和模拟器中工作正常。

Answer 1

所以我想通了.. 因为我正在维护这个遗产项目.. 序列化类 CustomAuxEffectStats 在构造函数中有很多引起问题的参数和很多getter，setter ...... 我删除了方法，并使所有字段级别。从构造函数中删除所有参数... 一切都很好。
